Research Methodology

Paper Solution oct - 2009

Q.1. Answer the following

1. Define Research and give classification.

A. Research is the systematic process of collecting and analyzing information to increase our understanding of the phenomenon under study.

According to Redman Y Mory, ‘Research is a systematized efforts to gain new knowledge’.

Research is classified as follows:

Descriptive Vs Analytical Research

Applied Vs Fundamental Research

Quantitative Vs Qualitative Research

Conceptual Vs Empirical Research

2. What do you mean by variable? List out various types of variable.

A. Variable is an object or event that can take on more than one form or value. Variable is a measurable factor that can assume more than one value. Eg: Age, income, gender, etc.

Types of research are:

Independent variables

Dependent variables

Controlled variables

Intervening variables

Extraneous variables

3. Explain the term ‘Panel’.

A. Group of people with certain qualifications, selected for a specific purpose and limited time, and usually disbanded thereafter.

4. Explain various types of information.

A. Various types of information are as follows:

1. Facts

2. Quasi Facts

3. Awarness or penetration of information

4. Opinions

5. Attitudes

6. Future action plans

7. Reasons

5. Define scaling and state various types of scale.

A. Scaling is th branch of measurement that involves the construction of an instrument that associates qualitative constructs with quantitative metric units.There are four type of scale:

1. Nominal scale.2. Ordinal or rank scale.3. Internal scale.4. Ratio scale.

6. What is coding?

A. Coding is the procedure of classifying the answers to a question into meaningful categories. The symbols used to indicate these categories are called codes. It is necessary to carry out the subsequent operations of tabulating and analyzing data.

7. What is sampling error?

A. Sampling error is the gap between sample mean and population mean. Sampling error occurs because of chance variation in the scientific selection of sampling units. As a sample size increase sampling error decreases.

Q.2. a) Distinguish between scientific and non-scientific method.

A: The comparison between scientific method and non scientific method is as follow:(a) Objectively (b) Degree of Accuracy (c) Continuing and exhaustive

(a) Objectively Scientific method is more objective as compare to Non-Scientific

method.(b) Degree of Accuracy

Scientific method ism more precise as compare to Non- Scientific method.(b) Continuing and Exhaustive

Scientific method takes existing knowledge which forms to be continuous and unending.

b) Explain types of research design.

A: Types of resource design

1. Exploratory research designThe exploratory research design is focus on the discovery of ideas. Exploration is particularly useful when researchers useful when researchers lack a clear idea of the problems they will meet during the study. When the researcher don’t know about the problems & to know the additional information.

The area of investigation may be so new or so vague that a researcher needs to do an exploration just to learn something about the dilemma facing the manager important variables may not be known or thoroughly defined hypotheses for the research may be needed.

An exploratory study is generally based on the secondary data that are readily available. It dose not have a formal and rigid design as the researcher may have to change his focus or direction, depending on the availability of new ideas and relationship among variables.

The design of exploratory studies is characterized by great flexibility and ad hoc versatility. The researcher is invoked in investigating an area or subject about which he or she is not sufficiently knowledgeable to have formulated

Controlled Experiments

Natural Experiments

Descriptive Research Design

Longitudinal Studies

Research Design

Exploratory Research Design

Cross sectional studies

detailed research questions and to state hypotheses about it. Exploratory dose not involve probability-sampling plans.

2. Descriptive research design:-At the name it self revels that it is essentially a research to describe some thing. It may also use for predicting purposes.

->description of phenomena or characteristics associated with subject population. ->estimate of proportion of a population that have these characteristics. ->discovery of association among different variables (correlation study).

Decision makers. Descriptive studies can be divided into two broad categories—A. cross sectional B. longitudinal

A. CROSS SECTIONA: The studies measure units samples of the population at one point.A cross sectional studies are carried out once and represent a snapshot of one point of time. A cross sectional study is concerned with a sample of elements from a given population.In multiple cross sectional design only one sample of respondents is drawn from the target population, and information is obtained from this sample only once.In multiple cross sectional design, there are two or more samples of responds, and

1. Field study:- Includes depth study. Field study involves an-in depth study of

problem. Field studies are ex-post-facto scientific inquires that aim finding the relation and inter relation among variables in a real world environment setting.Example; reaction of India men towards branded reaction ready-to-wear suitStrength: they are close to real life , and they can’t be criticized on the ground that they remote from real setting or are artificial.Weakness: One of their major weakness is their ex-post facto character. As a result interrelations among variables are weaker than they are in laboratory experiments’. A there are several variables affecting the response of interest, such studies find it.Field Survey: Large sample are a feature of the study field survey require good knowledge like constructing a questionnaire sampling technique used act. Also it is obvious that a sample survey needs less time than a census inquiry.(b) Longitudinal Studies: longitudinal studies are repeated over an extended period. Longitudinal studies involve panels. Panels are sample respondents who provide information at regular interval over an extended period of time.

Tow type of panel:-1. True panel :-

This involves repeat measurement of the same variables.

2. Omnibus panel :- In ominous panel too a sample of elements being selected & maintained but the info collected from the member variable. Consumer attitude to words chine made product.3. Causal research design :- At name implies a casual design investigate the casual & effect relationship between two or more variable.

(A) concomitant variable :- A condition for inferring causality that requires that the extent to which a cause x & effect y occur together as predicted by the hypothesis under consideration.

(B) Time order of occurrence of variable :- The time order of occurrence condition states that the causing event must occur their before of simultaneously with the effect it can’t occur aster word it is possible for each event in a relationship to be both a cause & an effect of the other event.

(C) elimination of other possible caudal factor:- It means that the factor or variable

being investigated should be the only possible causal explanation in other word when to or more cause of a given phenomenon have one only one condition is common then that condition may be regarded as the causal.

Natural experiments(1) Time series & trend analysis:-

In a time series design data are obtained from the same sample or population at successive intervals time series data relate to the same sample trend data relate to matched sample drawn from the population at successive intervals.

(A) the one shot case study :- The design is also known as the ‘try out’ design it is

Simplest & can be shown symbolically as follows.X O

Where ‘x’ indicated the exposure a subject or group to an experimental treatment whose effect is to be observed & ‘o’ indicates the observation or measurement take on the subject or group after am experimental treatment.

(B) Multiple time series:- Another time series involves the control group symbolically.

O1 O2 O3 X O4 O5 O6O’1 O’2 O’3 O’4 O’5 O’6

It fails to control history & there may be certain environmental changes in the later period which may affect the effectiveness of result.

(2) Cross section designs In the cross sectional design the effect of different levels of treatment are measure

on several groups at the same time. Symbolically a cross sectional design may be shown as bellow:

X1 O1X2 O2X3 O3X4 O4

The impact of varying levels of treatment is studied on the basis of the sales of the product in different territories.

There may be some extraneous factor which may affect the sale in a particular territory.3. Combination of cross sectional & time series design:

O1 X O3O2 O4

These design as the name implies, cross sectionalTime-series & cross-sectional design while there can be May variant a more frequently use design is the ex-post-facto test control group.2. Controlled experiment (1) After only with control group

R X o1R o2

It has been criticized on the ground that it does not concern itself with the pretest. However, by avoiding the pre-test. The design provides control over the testing & instrument effect.(2) Before after with control group.

R o1 x o2R o3 o4

As the two before measurements, o1&o3&the two after measurements o2 & o4 are made at the same points in time the design is able to control history with the help of this design, one can measure the effect of treatments in three ways o2-o1,o2-o4 & (o2-o1)-(o4-o3) (3) Four groups -six study design

The symbolically the design can be show as follows R O1 X O2R O3 O4R X O5R O6

The effect of treatment can be measured in several ways such as o2-o1, o4-o2,o0-o5,o1-o3&(o1-o2)-(o4-o3) the after measurement can be show in a 2*n matrix as follows.

No.x xB. measurement taken o4 o2No before measurement taken o6 o5

The difference between the rows must indicate the bases for estimating the testing effect.

Q.2. a) Distinguish between primary data and secondary data.

A. difference between primary data and secondary data are:

Primary data Secondary data1 There are original data gathered by the

researcher for the project at a hand.1 They are the data already existing in

the file or in other form gathered for any other project.

2 It is the source which originate in time data

2 It is the source that secure the data from the original source.

3 They are more complete and accurate. 3 They may be inaccurate. Unsatisfactory as per situation.

4 It relates specifically to the problem at hand.

4 They are called historical data.

5 The main disadvantage is the cost and time required to collect them.

5 It is cheaper and fast.

6 Sources are: Internal: Personal interviewExternal: Retailer, customer, competitors.

6 Sources are:Internal: Include company recordsExternal: Libraries, trade associations, government publications.

7 It is accumulated to meet up the research objective of the subsisting project.

7 It was collected to convene the requirement of various research objectives.

8 It shows latest information. 8 It lacks aptness.

b) Explain various steps involved in research design.

A. Steps in the Research Design Process

Step 1: Define the Research ProblemProblem definition is the most critical part of the research process. Research problem definition involves specifying the information needed by management. Unless the problem is properly defined, the information produced by the research process is unlikely to have any value. Coca-Cola Company researchers utilized a very sound research design to collect information on taste preferences. Unfortunately for Coca-Cola, taste preferences are only part of what drives the soft drink purchase decision.

Research problem definition involves four interrelated steps: (1) management problem / opportunity clarification, (2) situation analysis, (3) model development, and (4) specification of information requirements.

The basis goal of problem clarification is to ensure that the decision maker’s initial description of the management decision is accurate and reflects the appropriate area of concern for research. If the wrong management problem is translated into a research problem, the probability of providing management with useful information is low.

Situation AnalysisThe situation analysis focuses on the variables that have produced the stated management problem or opportunity. The factors that have led to the problem/opportunity manifestations and the factors that have led to management’s concern should be isolated.

A situation analysis of the retail trade outflow problem revealed, among other things, that (1) the local population had grown 25 percent over the previous five years, (2) buying power per capita appeared to be growing at the national rate of 3 percent a year, and (3) local retail sales of nongrocery items had increased approximately 20 percent over the past five years. Thus, the local retailers sales are clearly not keeping pace with the potential in the area.

Step 2: Estimate the Value of the InformationA decision maker normally approaches a problem with some information. If the problem is, say, whether a new product should be introduced, enough information will normally have been accumulated through past experience with other decisions concerning the introduction of new products and from various other sources to allow some preliminary judgments to be formed about the desirability of introducing the product in question. There will rarely be sufficient confidence in these judgments that additional information relevant to the decision would not be accepted if it were available without cost or delay. There might be enough confidence, however, that there would be an unwillingness to pay very much or wait very long for the added information.

Step 3: Select the Data Collection ApproachThere are three basic data collection approaches in marketing research: (1) secondary data, (2) survey data, and (3) experimental data. Secondary data were collected for some purpose other than helping to solve the current problem, whereas primary data are collected expressly to help solve the problem at hand.

Step 4: Select the Measurement TechniqueThere are four basic measurement techniques used in marketing research: (1) questionnaires, (2) attitude scales, (3) observation, and (4) depth interviews and projective techniques.

P r i m a r y M e a s u r e m e n t T e c h n i q u e s

I. Questionnaire – a formalized instrument for asking information directly from a respondent concerning behavior, demographic characteristics, level of knowledge, and/or attitudes, beliefs, and feelings.

II. Attitude Scales – a formalized instrument for eliciting self-reports of beliefs and feelings concerning an object(s).

A. Rating Scales – require the respondent to place the object being rated at some point along a numerically valued continuum or in one of a numerically ordered series of categories.

B. Composite Scales – require the respondents to express a degree of belief concerning various attributes of the object such that the attitude can be inferred from the pattern of responses.

C. Perceptual maps – derive the components or characteristics an individual uses in comparing similar objects and provide a score for each object on each characteristic.

D. Conjoint analysis – derive the value an individual assigns to various attributes of a product.

I. Observation – the direct examination of behavior, the results of behavior, or physiological changes.

II. Projective Techniques and Depth Interview – designed to gather information that respondents are either unable or unwilling to provide in response to direct questioning.

A. Projective Techniques – allow respondents to project or express their own feelings as a characteristic of someone or something else.

B. Depth Interviews – allow individuals to express themselves without any fear of disapproval, dispute, or advice from the interviewer.

Step 5: Select the SampleMost marketing studies involve a sample or subgroup of the total population relevant to the problem, rather than a census of the entire group.

Step 6: Select the Model of AnalysisIt is imperative that the researcher select the analytic techniques prior to collecting the data. Once the analytic techniques are selected, the researcher should generate fictional responses (dummy data) to the measurement instrument. These dummy data are then analyzed by the analytic techniques selected to ensure that the results of this analysis will provide the information required by the problem at hand.

Step 7: Evaluate the Ethics of the ResearchIt is essential that marketing researchers restrict their research activities to practices that are ethically sound. Ethically sound research considers the interests of the general public, the respondents, the client and the research profession as well as those of the researcher.

Step 8: Estimate Time and Financial Requirements

The program evaluation review technique (PERT) coupled with the critical path method (CPM) offers a useful aid for estimating the resources needed for a project and clarifying the planning and control process. PERT involves dividing the total research project into its smallest component activities, determining the sequence in which these activities must be performed, and attaching a time estimate for each activity. These activities and time estimates are presented in the form of a flow chart that allow a visual inspection of the overall process. The time estimates allow one to determine the critical path through the chart – that series of activities whose delay will hold up the completion of the project.

Step 9: Prepare the Research ProposalThe research design process provides the researcher with a blueprint, or guide, for conducting and controlling the research project. The blueprint is written in the form of a research proposal. A written research proposal should precede any research project.

Q.3. a) Explain the term Data. What points should be considered by the researcher before using secondary data?

A. Data: Data refers to a collection of natural phenomena descriptors including the results of experience, observation or experiment, or a set of premises. This may consist of numbers, words or images, particularly as measurements or observations of a set of variables.

The points to be considered by the researcher before using secondary data are:

Availability: The first and foremost requirement is that secondary data must be available for us. At times, one may find that secondary data are not available on a problem at hand. In such cases there is no alternative but to take recourse to the collection of primary data.

Relevance: Relevance means that the data available must fit the requirements of the problem at hand. This would cover several aspects.

The unit of measurements should be the same as that in the research problem

The concepts used should be the same as are imagined in the problem

Another pertinent issue is that the data should not be obsolete.

Accuracy: This would not only enable the researcher to get core comprehensive information but would also indicate the context in which

data have been collected, the procedure followed and the extent of care exercised in their collection.

Sufficiency: Finally the data should be sufficient. If the data are inadequate, then compliance with the preceding requirements will be in vain.

b) Explain the field experiments of collecting primary data.

Ans: Field experiments:Studies which are carried out in the natural environment be that a hospital,

a school, or the street, are known as field studies or field experiments. In field experiments the researcher is testing hypotheses in a similar way to the way it would be done in the laboratory. The main difference is that many of the extraneous variables the researcher would be able to control in the laboratory are not able to be controlled in the field.

Field experiments are those that are conducted in real world with the subjects who are unaware of their participation. That is natural setting is the base of field research experiments.

Merits of Field experiments:1. Real life conditions: the field experiments are conducted under real life

conditions and not under artificial situations.2. Wider and large participation: under field experimentation, the setting

allows maximum number of participants so that the findings are put to more rigorous conditions.

3. There is no need to create artificial conditions: creation of artificial conditions is a costly affair. It is alike shooting a scene for a film open door which is more natural and not really costly,.

4. Benefits of variable observations: the units or subjects are not constantly observed so that each time same results are not repeated. The business variables are constantly changing. That makes the experimenter to change his stand each time to the changing conditions as it is impossible to control them.

Demerits of field experiments:1. Time consuming exercise: conducting experiments in field setting is a

time consuming affair. The experimenter may not be able to test his finding in time and report to the user. Time dimension is very important in business foe time is more than money.

2. Experiments are not widely acceptable: field setting experiments do not allow standard or conditions rigidly followed. Therefore reliability of results is doubtful.

3. Field experiments are not possible without quantification: in a dynamic field like marketing, there are many variables which cannot be

quantified are not subject to accurate measurements in terms of results.

Q.3. a) Explain the sources available for gathering secondary data.

A. Sources of secondary data are:

1. Internal data sources:

a. Accounting Records: Accounting records generate a good deal of data. As profits are based on sales, sales invoice is a good source. Normally a sales invoice includes name and address of the customer, items ordered, quantities and qualities shipped, discount allowed, price charged, total amount of sales and the data of sales. Such information can be extremely useful in undertaking a detailed analysis of sales by product, customer, industry, geographic area, sales territory and sales representative.

b. Sales and marketing reports. These can include such things as:

Type of product/service purchased

Type of end-user/industry segment

Method of payment

Product or product line

Sales territory

Salesperson

Date of purchase

Amount of purchase

Price

Application by product

Location of end-user

c. Internal Expert opinion: Experts working in the company can also be a good source of internal data. Executives working as product manager, marketing research managers, public relations personnel and advertising personnel have specialized knowledge relevant to marketing problem.

d. Miscellaneous reports. These can include such things as inventory reports, service calls, number (qualifications and compensation) of staff, production and R&D reports. Also the company’s business plan and customer calls (complaints) log can be useful sources of information.

2. External Data Sources:

a. Government Publications: A large bulk of secondary data useful to a marketing researcher is found in various government publications. The Registrar General of India conducts a population census throughout the country every 10 years and brings out demographic data in voluminous reports. The Central Statistical Organization brings out statistic of national income. The Director of Commercial Intelligence, Government of India brings out monthly statistics of the foreign trade of India. Some other official publications included are: Reserved Bank of India Bulletin, Currency and Finance Report, Agricultural situation in India, The Indian Labor Journal, etc.

b. Non-Government Publications: There are number of private organizations which brings out statistics in one form or another on a periodical basis. Various Industry and Trade Associations are important. Another source of information is the stock exchange directories, the Market Research and Statistical Bureau, etc. Besides industry associations several chambers of commerce are also a source.

c. Syndicated Services: Syndicated services are provided by certain organizations, which collect and tabulate marketing information on a continuing basis. Reports based on marketing information collected by such organizations are sent periodically to clients who are subscribers. Syndicated services are normally designed to suit the requirements of many individuals or firms. Such services are particularly useful in the spheres of TV viewing, magazine, readership and the movement of consumer goods through retail outlets.

d. International Institutions Publication: There are several international organizations that publish statistics in their respective areas. Some of these organizations publish data on India among with that of other countries. Bank, economic reviews, university research reports, journals and articles are all useful sources to contact.

e. Libraries: There are two types of libraries- public library and private libraries. Private libraries are those which are maintained by some business firms. Public libraries are maintained by the government that can be utilized by any research from general public.

f. Business Firms: Researcher depends on certain business firms for some necessary information. Business reports are sometimes of great value of the researchers. Researcher can collect information from bank and insurance companies on request.

g. Consumer Research Services: Usage and attitude studies, Brand image and positioning research, New product development research, Advertising

research, Product testing, Simulated test marketing, Market estimation and forecasting, market modeling, customized panel research, etc.

b) Explain various methods of observation and applicability of observation method.

A. Various methods of observation are as follows:

1. Structured-Unstructured observation: Structured observation is used when the researcher problem has been formulated precisely and the observation have been told specifically what is to be observed. They may be given a simple form to record their observations. Unstructured observation implies that observers are free to observe whatever they think is relevant and important. While structured observations are free from subjective bias, unstructured observations are subject to this limitation.

2. Disguised-undisguised: The subjects do not know that they are being observed in case of disguised observation. In some cases it may be made by the observer by posing as one of the shoppers who are being observed. It may be difficult to completely disguise an observation, through this apart; it poses an ethical question of its desirability when those who are being observed are kept in the dark.

3. Observation under natural setting – laboratory setting: observations in field studies in their natural setting and are therefore undertaken in extremely realistic conditions. Sometimes an experimental manipulation may be introduced in a field study. Observational studies in laboratory settings have certain advantages over field studies. They enable the collection of data promptly and economically and in addition, permit the use of more objective measurements.

4. Direct – Indirect observation: In direct observation the event or the behavior of a person is observed as it occurs. In contrast indirect implies that record of past behavior is observed.

5.Human Mechanical Observation: Another way of classifying observation is whether they are made manually or by machines. Most of the studies in marketing research based on human observation wherein trained observers are required to observe and faithfully record their observation.

In some cases mechanical devices such as eye camera’s and audio meters are used for observation.

Q.4. Write short note

1) Telephone interview.

A: Telephonic interview:-Under this method , the researcher establishes

the contact trough telephone. In this interview the investigator ask selective question and it must be brief, simple to the point and non-confidential. Telephone interview are easy to administrator and allow data will be collected quickly at a relatively low cost. The interview can clarify the questions.

Advantages of self administered survey are:1) It is economical: it is the speediest method of data collection where up to date

information is got at telephone call without waste of time just sitting in the office.

2) Unbiased data: normally respondents are more frank on telephone than in person. They arre not influenced by family members and friends as telephone conversion is considered to be private affair.

3) Best method to elicit information from specific group: when the respondents are belonging to higher socio-economic classes, it is really very difficult to get personal appointment.

4) Quick response is possible: as the respondent is caught on phone with the prior appointment the information is available within a few minutes.

2) Personal interview:

A: Personal interview:-Personal interview is the process of communication where face

to face contact between the investigator and respondent is established. It is the conservation arrange for the purpose of obtaining views of respondent on the topic of inters to the interviewer.Merits:

1) It is Superior method: Personal interview method is superior to mail and telephonic interview method because it has two special features of its own: answer is got only on asking and personal observation.

2) Maximum information is sought: Maximum and accurate information can be elicited by the investigator because, he can explain each question in person and this enables the respondents to answer the questions only after understanding.

3) Regulation of interview: in personal interview the investigator being an active participant can control the interview to his advantage and to the convenience of the respondents by directing, guiding and supervising the respondents.

4) Greater degree of accuracy: the research results can be projected to the relevant universe or population with greater degree of accuracy because the

researches can procure good deal of information from horse’s mouth of different dimensions.

Demerits:1) It is expensive method: this method works out costly because of varieties of

expenses incurred on sampling, questionnaire, interviewing, recruiting- training and controlling investigators, paying for their services.

2) More administrative problem: personal interview method involves more administrative problems because of wider organizational paraphernalia selection, training and control of personnel both research and non research.

3) Biased information: the investigators may not get accurate and unbiased information though it is possible to get maximum information. It is likely to be biased as the investigator plays more active role in explaining ht questions; he may get answers only to the key questions and the rest he may manage as per his sweet will and caprice.

4) Time consuming method: it is not only expensive in terms of talent and in terms of talent and treasure but in terms of time. Survey research is not a straight jacket formula. Once the research problem is identified the researcher is to design questionnaire collect the data either higher himself or his team of investigator analyze the data and interpret.

Q.4. a) Compare Census and Sample Survey.

A. Census:

All items in any field of inquiry constitute a universe or population. A complete enumeration of all item in the population is known as census inquiry.

- When all items are covered high accuracy is obtained.

- Detailed information of respondent.

- Requires preparation of questionnaire, evaluation, relevance of secondary data, skilled researcher, deal of time, money and energy

- Great deal of difficulty because of resource involved.

Sample:

A sample survey is a survey where a few number of sample are selected from universe and they represent the whole population.

- As few items are taken, it becomes less expensive

- Saves time and energy

- The survey of sample would be misleading and conclusion would not be arrived

- Researcher has short time which may not prove useful.

b) Explain sampling process.

A: Following are the steps in sampling process

Define target population: Sampling design begins by specifying target population. Target population is collection of elements that posses the information for which the researcher is searching.

Identifying sample frame: A Sample frame is a representation of elements in the target population Eg: Tele phone directory.

Specifying sampling unit: Sampling unit is the basic unit containing elements of the target population.

Specifying sampling method: It indicates how sample units are selected. One of the most important decisions is to decide whether the sample will be probability sample or non probability sample.

Determine sample size; It refers to the no. of elements to be included in the study.

Execute sampling process: After selection of the execution of sampling process is required.

c) Discuss any one attitude scale.

A: (1)Nominal scale: Nominal scales are more widely used than any other scale for research in social science. In such a scale the numbers serve as labels to identify persons, object or events. It simply implies classification of items into two categories. In nominal scale the only operation involved is counting of number in each group.Advantage:

It is useful in preliminary or exploratory stage of the research. It is useful to know broad dimension of certain criteria.

Limitation: There is no rank order. NO mathematical operation. It is unsuitable for determining the relationship.

Q. 5. a) Explain data processing cycle.

b) Explain any one probability and non-probability design.

A. Probability design:

Simple random sampling: Simple random sampling is the simplest type of sampling in which we draw a sample of size n in such a way that each of N members of population has the same chance of being included in the sample.

Most frequently used method for simple random sampling is the random number table. Other method is not so much practical but it can also be used. Suppose in a class 100 students are there out of which 10 students needs to be selected randomly we can select in an order of ID like 6, 16,…,96.

Simple Random sampling in practice:

1. When a small sample is needed from the list of sample frame.

2. The cost per interview is practically independent of the location of the sample item.

Non Probability design

Convenience: Researcher has freedom to choose whomever they find thus the name is convenience. Sometimes called grab of opportunity sampling this is the method of choosing items arbitrarily and in an unstructured manner from the frame. Though almost impossible to treat rigorously it is the method most comm0only employed in many practical situations. In social science research, snowball sampling is a similar technique where existing study subjects are used to recruit more subjects in to sample.

c) What do you mean by Statistical estimation?

A. Statistical estimation involves the estimation of parameters for a population from a sample. This can be illustrated best by examples. Suppose a department store is interested in setting up a branch in the suburbs of a metropolitan city and would like it to be situated in a locality where the average income of the inhabitants is more than the national average. It will be too expensive apart from being extremely time consuming, to contact each household in that locality to find out its income and then to compute the average income of households. In such a case a sample of households is chosen, these households are contacted and the sample average income is computed. This sample average is then taken as an estimate of the average income of households in that locality.

Apart from knowing the average household income in the locality the department store may be interested in knowing the variability of the incomes. This would give it some idea of the price range of the products it should sell. Since it does not know the dispersion in the household incomes in the population it may use the sample standard deviation instead.

In both these examples a sample value has been used as an estimate of the population parameter. In the first example the sample mean is used as an estimator of the population mean. In the second example, the sample standard deviation is used as an estimator of the population standard deviation.

A point estimate is a single number estimate and is the simplest to calculate. However it will be only by chance that such a point estimate will be the same as the population parameter. This is because a number of samples of a given size can be drawn from the same population and these samples will give different point estimates of a true population parameter. This poses a problem as to how one can ensure a good estimator.

Q. 5. a) Explain types of question.

A. Types of questions are as follows:

1. Open ended questions: these are questions where respondents are free to answer in their own words.

2. Close ended question: it present a set of fixed alternative from which proper alternative can be chosen.

3. Dichotomous: structured questions with only two response answer or alternative.

4. Direct and indirect questions: direct question is one which can be asked and can be answered directly. Question carries a very clear indication such question can be answered exactly and easily as it is free from ambiguity. While indirect question are asked indirectly to allow respondent gazing and perceives the situation differently as per personality characteristic.

5. Scale type question: Scale type question are very popular in conducting marketing research. Respondent are given the range of categories in which to express their opinion. Scale is used to measure level or degree of attitudes or agreed upon opinion.

6. Descriptive question: Descriptive question can be attended by descriptive answer. It needs the detailed explanation. At the end of every descriptive question adequate space has been given to write the answer.

7. Short question: Short question can be answered just by writhing words. Question may be lengthy but can be answered by one or more words.

8. Rank order list: Here the respondents are asked to rank options from the most important to the least important option.

9. Check list: Such question involves more option and can be answered by selecting one or more options.

10.Multichotomous: Such types of questions involves more options may be 5 or more and respondent are asked to select anyone by tick mark. They are not required to write any word.

b) Prepare a questionnaire on consumer attitude regarding e-banking.

Q.6. Write notes

1) Audience for research report

A. The first point to be considered while writing a research report is that for whom the research is going to be prepared. So the language, style, size etc. of the research report should be according to the audiences. The respondents of the research report will be of different backgrounds. It is therefore necessary to understand who can be the possible respondents.

Client: Clients are those persons who refer the research report for solving any problems in the organization. For e.g.: marketing manager may feel the need of studying the buying behavior of the customers.

Researcher: The researcher will keep one or two master copies for reference. This copies can be prepared in technical or classical language of business research.

General Public: Apart from clients and researchers, the research report can also be read by the general public. It can be for various reasons, it can be usefull for students, lecturers, etc.

2) Measures of central tendency

A: The principal measure of central tendency is the arithmetic mean, the median, and the mode.

The arithmetic mean should be used In case of itervalled or ratio-scaled data. It is obtained by adding the observation and dividing the sum by the number of observation.

o In case of a frequency distribution the arithmetic mean is obtained by the

following steps:

The mid-point of each class interval or category is multiplied by the number of observation the class interval.

The resultant values are summed up.

The total thus obtained is divided by the total number of observation.

o The median I measure of the central item when all the items in a series

are arranged either in ascending or descending order of magnitude.

o The mode is another measure of location of a frequency distribution. It is

the value at the point around which the items are most heavily concentrated.
