Let's assume you are using these results as an estimate of effect size for the sample size you will need for your next study. Based on this power and sample size analysis, how many total cases would you need to collect in order to perform the same analysis with sufficient statistical power in that next study. approximate correlation power calculation (arctangh transformation) n = 57.42466 r = 0.36 sig.level = 0.05 power = 0.8 alternative = two.sided

Step 1
We are given the following information: - Sample size (n) = 57.42466 (approximately 57) - Correlation coefficient (r) = 0.36 - Significance level (α) = 0.05 - Power (1 - β) = 0.8 - Alternative hypothesis = two-sided Show more…

You plan to conduct a study where your nondirectional hypothesis will be assessed with a t test for independent means at the .05 significance level. If you are predicting a medium effect size, how many participants would you need in total (assuming equal Ns for each of the two groups) to obtain 80% power? See table on pg. 295. 1) 128 2) 100 3) 50 4) 64

Chad is planning to conduct a study with an estimated effect size of .55. The appropriate analysis for this study is a two independent samples t-test. A) What is the total number of participants needed to have a power = 0.91? (Use alpha = 0.05, two-tailed) B) Using Cohen's special conventions, how would you characterize an effect size of .55? Amy conducted a single sample experiment. The effect size is 0.32 and sample size is 25. (Use alpha=.05; two tailed) A) What is the power of this example? B) Interpret/discuss your answer to the above question. That is, what does power mean in the context of testing a hypothesis?
