This week we have reviewed a Power Analysis and it components. For discussion board this week, please review the article I have posted in the course shell by Voss et al. (2004) titled "Sedative music reduces anxiety and pain during chair rest after open-heart surgery." Once you review the article, please answer the following questions. You may certainly comment on a peers posting, but it is not required for this week. Under the methods section (on page 198) the researchers describe their use of a Power Analysis to justify sample size. Please answer the following questions: What was the target sample size suggested by the Power Analysis? Why did the researchers exceed this value? What effect size did the researchers use to calculate (determine) the sample size? What was this study powered at? What was the level of significance used by the researchers?
