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.
