Review the \”Sample Size\” Topic Material. Assume you want to do a project that compares the survey results before an intervention to those after an intervention in the same sample (the same people will take both surveys). You plan to use a paired t-test to analyze your results. Identify and select a tool of your choice to conduct the sample size calculation. You may use your SPSS Statistical Package for the Social Sciences, but it is not required for this assignment. Perform a sample size calculation to determine how large your sample should be. Justify your sample size calculation with citations. Discuss how your sample size may affect the validity of your project.
