Week 5 Assignment
Course Project Worksheet – Calculating Sample Sizes Using G* Power
Using the G* power website, download the free software and conduct a G* power analysis using the provided data.
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.
Figure 1 – Effect Size Benchmarks
Statistic Small Medium Large
Means – Cohen’s d 0.2 0.5 0.8
ANOVA – f 0.1 0.25 0.4
ANOVA – eta squared 0.01 0.06 0.14
Regression f-test 0.02 0.15 0.35
Correlation – r or point serial 0.1 0.3 0.5
Correlation – r squared 0.01 0.06 0.14
Association – 2 x 2 table – OR 1.5 3.5 9
Association – Chi-square – w or Phi 0.1 0.3 0.5

Week 6 Assignment
Course Project Worksheet –Choosing the Correct Statistical Test
An important component to hypothesis testing is choosing the appropriate test to compute the test statistic. 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.
Statistical Test Definition/Explanation Levels of Measurement
Basic T-Test
Independent Sample T-Test
Paired T-Test
Analysis of Variance (ANOVA)Test
Chi-SquareTest
Regression Test
