Problem Definition, Objectives, and Research Questions
If you do not know where you are going,any road will take you there.

“The formulation of the problem is often more essential than its solution”
-Albert Einstein

Two Types of Problems
Management Decision ProblemWhat decision makers need to do
Sales are on the decline
Customer base is aging and younger consumers prefer competitor’s brands
Research ProblemSpecifies information needed to address managerial problems & how it can be obtained

MDP
Action Oriented
Focus on symptoms
Should new product be introduced
Should advertisement be changed
Should price be increased
Research Problem
Information oriented
Focus on underlying causes
Determine consumer preferences
Determine effectiveness of current ad.
Price elasticity of demand

Research Objectives
Research objectives address information gaps that must be closed so the manager solves the marketing management problem
Each research objective must be precise, detailed, clear, and operational
Example: “Compare the demographic profiles of AT&T buyers to nonbuyers using age, sex, education, and annual family income.”

Research QuestionsA research question is the researchers’ paraphrase of the research objective(s) in the form of a question.
Example:
“Are AT&T’s non-buyers different demographically from AT&T’s buyers?
Or better yet:
“Are AT&T’s non-buyers younger than AT&T’s buyers?”
Specific questions are better

Research Hypotheses
A hypothesis is an unproven proposition or supposition that tentatively explains certain facts or phenomena; a probable answer to a research question.
Hypotheses are statements about the nature of the world. They are guesses.
Example: “AT&T’s non-buyers are younger than AT&T’s buyers”
![Page 11: Problem Definition in research design](https://reader035.vdocuments.mx/reader035/viewer/2022081413/5463f9b2af7959f6118b6410/html5/thumbnails/11.jpg)
Research HypothesesNull Hypothesis: Conservative statement about the status quo. It is what our research is set out to disprove.
H0: AT&T non-buyers do not differ in age from AT&T buyers
Alternative Hypothesis: A statement that states the opposite of the null hypothesis.
HA: AT&T non-buyers are younger than AT&T buyers
