Learning Objectives for Chapter Three – Generating and Refining Research Hypotheses
1. Define1 hypothesis.
2. List1 five strategies for generating research ideas that involve questioning either folk wisdom or informal observation. Rank6 the five in terms of how valuable they would be for helping you develop a research hypothesis. Using one of those five strategies, generate5 a research hypothesis.
3. Describe2 three advantages of deriving research ideas from previous research.
4. Define1 double-blind technique and explain2how replicating a study using the double-blind technique can result in a studythat has greater validity than the original study.
5. Explain2 how looking for moderator variables can help reconcile studies that appear to produce conflicting results.
6. List1 seven ways to generate research ideas from previous research. Rank6 the ways in terms of how useful you think they are. Use3one of them to generate a research idea.
7. Define1null hypothesis.Explain2 why the null hypothesis cannot be proven.
8. Illustrate3 the steps involved in converting an idea into a research hypothesis. Examine4 the role that each of the following terms play in your illustration:
● supportable (be sure to refer to the null hypothesis)
● relevance (be sure to refer to theory)
9. List1 10 strategies you can use to refine a hypothesis. Rank6 them in order of usefulness.Use3 one to refine one of your hypotheses.
10. Explain2 the advantages of basing a research idea on theory.Generate3 a hypothesis based on dissonance theory.
11. Define1mediating variable. Explain2 how a hypothesis about how a mediating variable accounts for a treatment’s effect can be a more interesting hypothesis than one that merely hypothesizes that the treatment will have an effect.
12. Define1moderating variable. Distinguish4 moderating variable from mediating variable. Explain2 how a hypothesis about how a variable moderates atreatment’s effect can be a more interesting hypothesis than one that merely hypothesizes that the treatment will have an effect.
13. Define1functional relationship. Explain2 how a hypothesis about the functional relationship between treatment amount and treatment effect can be a more interesting hypothesis than one that merely hypothesizes that the treatment will have an effect.
14. List1five steps you can take to make testing your hypothesis more ethical. Rank6the steps in terms of their value to you.
15. List1one advantage and list one disadvantage of deciding not to manipulate variables.
