Statistics Chi Square Data Analysis Discussion Questions

SPSS required to complete. please see for ASSIGNMENT attachments and Discussion questions below (attachment are the guides/ example).

1. During this week’s lesson, you learned that the chi-square test is a nonparametric test. When

compared to parametric tests such as t or F, nonparametric tests tend to have less statistical

power than parametric tests. Explain why this is the case. Given this distinction, would a test

that has less statistical power increase the risk of a Type I error or a Type II error? Explain.

2. Is the chi-square goodness-of-fit test a univariate test or a bivariate test? In other words, does

it involve one variable or does it involve two variables? Explain.

3. Present a research question in an aviation context—other than the ones presented in the

guided example and graded assignment—that would be a good application of the chi-square

goodness-of-fit test. As part of your RQ include any corresponding operational definitions

and the targeted variable.
