Research Hypothesis

6175

So far

• Theoretical– Thesis

• Algorithm that solve real problems• Evaluation by mathematical proof

• Experimental– Project

• Demonstration• Evaluation by experiment

So far

• Looked at Theses

• Number & titles of chapters

• Citations– Direct quotes– References– Primary, secondary and tertiary sources

So far

• Types of Research studies• Selecting a Research Topic

– Areas that is starting develop

• Making an outline of Literature Review• Charts, graphs and tables

– Placing them– Writing about them

• Look at journal articles• Warning about plagiarism

Hypothesis

• A refinement of the research problem• Most specific statement of the problem• States the researcher’s expectations concerning

relationship between the variables in the research problem

• Researcher collects data; either supports or rejects the hypothesis.

• Hypothesis formulated following the review of literature but prior to the execution of study.

Hypothesis

• Stated in a way it can be tested.– Inductive hypothesis

• A generalization based on observation

– Deductive hypothesis• Derived from theory

• Stated as null hypothesis– The opposite of what is expected.– Then disprove (reject) the null hypothesis based on

findings.• The new algorithm does not improve performance

significantly.• Now disprove it.

Why students do not complete

• Procrastination

• Procrastination

• Procrastination

• Procrastination

Why students write poor theses

• Poor review of literature

• Not having an outline

• Not keeping good notes on what you read

• Do not write well– Use campus resources

Conferences

• Attend every conference

• Attend every theses and project defense

• Attend every presentation given by prospective faculty.

Homework

• What hypotheses were found in the theses you read?

• How did the researcher go about proving or disproving them?
