Suppose a clinical psychologist conducted a survey to determine if men and women have the same attitude toward the Adlerian Therapy process. A random sample of eight married couples is selected and the husbands and wives respond to the survey. The scores are as follows:
Husbands 16 20 10 15 8 19 14 15
Wives 15 18 13 10 12 16 11 12
1. For each group, calculate the sample size (N), mean ( ̅), standard deviation (s).
2. State the null and alternative hypotheses (H0 and H1).
3. Make a decision about the null hypothesis. a. Calculate the degrees of freedom (df). b. Set the alpha (α), identify the critical value (draw the distribution) and state the decision rule. c. Calculate the value for the t-test for independent means. d. Make a decision whether to reject the null hypothesis. e. Determine the level of significance.
4. Draw a conclusion from the analysis.
5. What are the implications of this analysis for the clinical psychologist?
