Learning
Objectives for Chapter Three Ð Generating and Refining Research Hypotheses

** **

## Pages 71-75

1. Define^{1} *hypothesis*.

2. List^{1 }five strategies for
generating research ideas that involve questioning either folk wisdom or
informal observation. Rank^{6} the five in terms of how valuable they
would be for helping you develop a research hypothesis. Using one of those five
strategies, generate^{5} a research hypothesis.

## Pages
74-80

3. Describe^{2} three
advantages of deriving research ideas from previous research.

4. Define^{1} *double-blind
technique* and explain^{2}how replicating a study using the
double-blind technique can result in a studythat has greater validity than the
original study.

5. Explain^{2 }how looking for *moderator
variables* can help reconcile studies that appear to produce conflicting
results.** **

6. List^{1} seven ways to generate
research ideas from previous research. Rank^{6} the ways in terms of
how useful you think they are. ** **Use^{3}one
of them to generate a research idea.

80-84

7. Define^{1}null hypothesis.Explain^{2}
why the null hypothesis cannot be proven.

8. Illustrate^{3} the steps
involved in converting an idea into a research hypothesis. Examine^{4} the role that each
of the following terms play in your illustration:

● testable

● supportable (be sure to refer to the null hypothesis)

● rationale

● relevance (be sure to refer to theory)

84-104

9. List^{1 }10 strategies you
can use to refine a hypothesis. Rank^{6} them in order of
usefulness.Use^{3} one to refine one of your hypotheses.

10. Explain^{2} the advantages of basing a research idea on
theory.Generate^{3} a hypothesis based on dissonance theory.

11.
Define^{1}*mediating
variable*. Explain^{2} how a hypothesis about how a mediating
variable accounts for a treatmentÕs effect can be a more interesting hypothesis
than one that merely hypothesizes that the treatment will have an effect.

12.
Define^{1}*moderating
variable*. Distinguish^{4 }moderating variable from mediating
variable. Explain^{2} how a hypothesis about how a variable moderates
atreatmentÕs effect can be a more interesting hypothesis than one that merely
hypothesizes that the treatment will have an effect.

13.
Define^{1}*functional
relationship*. Explain^{2} 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.

List^{1}five
steps you can take to make testing your hypothesis more ethical. Rank^{6}the
steps in terms of their value to you.

15.
List^{1}one
advantage and list one disadvantage of deciding not to manipulate variables.
