Following your initial memory research at BRRC, you implemented a new six-month low-cost intervention to try increasing residents’ memory capacity. You are disappointed to find that, although memory scores did increase, memory capacity on the post-test was not statistically significantly higher. BUT - You have a friend taking a graduate statistics class, and she suggests that you might not have had enough statistical POWER to detect a difference. After talking with her, you have a few ideas about what influences power. a. Explain THREE factors that would INCREASE the power of this study, and discuss how reasonable it would be to CHANGE each factor in this particular study. [15 points] b. Your friend helps you do a post-hoc “Achieved Power” analysis, and it shows that you did indeed have low power in your study. Can you use this as evidence that your program worked after all?
