I want you to show that you understand the methodology of the Paired-Samples t-Test.

(1) Create your own example of a Related/Paired Samples t-Test. You don't have to solve this example, but I want you to demonstrate that you understand the methodology (the way a study is designed) of the Paired-Samples t-Test.

Include the following:

IV:

DV:

Null Hypothesis:

Alternative Hypothesis:

I want you to show me that you know how to solve and interpret the results from a Paired - Samples t-Test.

A researcher studies the effect of cognitive psychotherapy on positive self-regard. The number of positive statements made about oneself is recorded for each participant during the first meeting. After 8 weekly therapy sessions, the measures are repeated for each person. The therapist predicts that cognitive psychotherapy will increase the number of positive statements. For the following data:

Before Treatment	After Treatment
7	10
6	12
9	7
5	17

Identify the IV and DV.
State the hypotheses.
Set the criteria for the decision (In other words, what is the t-critical value?).
Conduct the appropriate hypothesis test.
Make a decision about the null hypothesis. Should you reject the Ho?
Interpret the results. What do the results of your test tell you about cognitive psychotherapyand positive self-regard?
