Learning Objectives: 11-1: About the two types of dependent designs--matched and repeated measures. | 11-2: To identify the advantages and drawbacks of dependent designs. | 11-3: How to compute and interpret dependent-groups t tests.

Summary: This is a matched-group comparison of NBA players’ performance.

Questions to Consider:

1. What were the matching procedures for this design?
2. Why was matching a better choice than repeated measures or an independent-groups design?
3. Which of the matched-group comparisons were statistically significant (at p < .05)? What do these results suggest?

Learning Objectives: 11-1: About the two types of dependent designs--matched and repeated measures. | 11-2: To identify the advantages and drawbacks of dependent designs. | 11-3: How to compute and interpret dependent-groups t tests. | 11-4: How to compute the confidence interval and effect sizes for dependent t tests.

Summary: This is an experiment examining the benefits of a psychoeducation group. The article can be used to review concepts from chapters 10 and 11.

Questions to Consider:

1. Why did the researchers use both independent- and dependent-groups designs in this study? Identify and explain the procedure for each type of design.
2. What were the results of the dependent-samples t tests? What do these results suggest?
3. What were the effect sizes and confidence intervals associated with the dependent-samples analyses? How would you interpret these?
