Question: Using the “marital satisfaction” dataset:

Perform a multivariate test to determine whether husbands vs. wives had different levels of marital satisfaction, as assessed by four different measures (Q1, Q2, Q3, and Q4).

What was the overall power for the multivariate tests? What was the overall effect size (multivariate eta-squared)?

What percent of the variance in each of the four criterion variables can be explained by whether the question respondent was male or female (i.e., husbands vs. wives)? Based on your output, were the statistical assumptions of MANOVA met?

Produce a correlation matrix to show the inter-relationships between variables Q1, Q2, Q3, and \(Q4\). Based on this matrix, do you think MANOVA was an appropriate test to use in part A, and why?
