Background

During this week you will identify a research question created in Week 1 that would be best answered by any of the following statistical tests: z test, t test for single sample, independent samples t test, repeated measures t test, or Chi-Square test. This discussion will help you work towards your "Week 3 Assignment 2." If there are no research questions that fit any of these types of statistical analyses, decide on a new question before moving forward with the assignment.
