1. What type of analysis was conducted in this study? Was this analysis technique appropriate? Provide a rationale for your answer.

2. According to Figure 1, at which time was the average pain score for the guided imagery group most similar to the control group? Discuss the importance of this finding.

3. Discuss what each aspect of this result means: F(1, 26) = 4.406, p = 0.046.

4. Is the change in the pain scores after 12 weeks of guided imagery statistically significant for the intervention group? If yes, at what probability?

5. State the null hypothesis for the effect of guided imagery on pain scores for the subjects in the treatment group at 12 weeks. Should this null hypothesis be accepted or rejected? Provide a rationale for your answer.

6. How many means are being compared for the pain scores at 12 weeks?

7. What did the researcher set the level of significance or alpha (α) at for this study? When will study results be considered significant?

8. The researchers do not report the standard deviations associated with the means. Would you be interested in knowing the standard deviations? Provide a rationale for your answer.
