There are 4 types of power analysis (a priori, post-hoc, criterion, and sensitivity). For the purposes of this class, we will focus on a priori power analysis since it is most commonly used when designing a research study (Hunt, n.d.).
Using the following parameters, complete a G* power analysis:
Alpha= .05 Power= .80 Expected Effect Size= In Week 2 Discussion 2, we practiced using the “Which Stats Test” Sage Tool. Refer to the statistical test determined using that tool and select the large effect size for the appropriate test. (Note: if you aren’t sure which test to use, you can use the t-test family, correlation). You will not lose points for choosing the incorrect test. The point here is to determine a test, input the parameters into G*power, and explain the results.

In the second column, define and explain statistical test listed in the first column. Be sure to note when each test is used, why you would choose this test, and what the output tells us. Be sure to provide a rationale for each test choice, including variable types. Then in the third column, specify what level(s) of measurement each test is used with.

Earlier this week, in Discussion 1, you explored which test might be most appropriate given your chosen variables. Now is your time to practice running the statistical test and analyzing the data.
