statistics question, homework help

A response is needed for the question you answered for 5Q1

Randall, here’s what I think you are trying to do.

There are three groups of similar students. One is learning a skill using medical-based games. Another is learning using education-based games. And the third is learning using business-based games.

The measures of outcome are creativity, grades and performance (in extra curricular activities).

In MANOVA, the omnibus null hypothesis is that there is no difference in the multivariate group means. In other words, you cannot detect a difference in outcome between these groups using any combination of the three metrics.

The omnibus test, if significant, would then be followed by univariate tests (i.e., ANOVA) which have omnibus null hypotheses of the form: there is no difference in the group means measured by [creativity, grades, performance].

Each of the ANOVA’s can then be followed by post hoc tests to determine the nature of the individual group differences on each metric.

This is a process that systematically drills down from the overall multivariate model to individual group differences on each variable.
