Consider your dissertation research interests. Identify one categorical/nominal

Consider your dissertation research interests. Identify one categorical/nominal
scale IV with more than 2 categories, and three DVs that are measured
on continuous scales. Think of DV measures that probably are moderately
correlated with each other because they are measuring different
components of the same or similar concepts (e.g., three different
measures of academic performance). State the null and alternative
hypotheses based on this design (with a planned analysis using a one-way
MANOVA). (Research support is not required for this question.)
