Z, T, or Chi-Square Test Study
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 (see attached file title: MY assignment ): 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.
Discussion Assignment Requirements
Initial Posting – In your initial posting for this assignment, include the following:
· Identify an appropriate research question that would require the use of a z-, t-, or Chi-Square test to answer. Pick the question from the list created in Week 1 or identify a new question if there are no appropriate ones from Week 1.
