Question

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). What information would a one-way MANOVA provide you? What more would you want to know if you get significant results in the MANOVA? Why would this be significant to your research? (Research support is not required for this question.)

Explanation:

My research interest area is critical thinking. I could use a one-way Manova to analyze results from a study to determine whether critical thinking ability impacts academic performance, intellect and emotional capacity. For this study the variables would be as follows:

Independent Variable (the variable being assessed for effect on the dependent variable): critical thinking training (measured on a nominal scale) among three categories of participants – high school freshmen, high school seniors, and college seniors. These categories were selected because they each mark key transitional points in a students’ mental and emotional development as they prepare for post-school life.

Dependent Variables

DV1 : academic performance (measured on a continuous scale using student GPA scores)

DV2 : Intelligence (measured on continuous scale using IQ testing instruments)

DV3 : Emotional intelligence (measured on a continuous scale by using prepared EQ testing instrument)

The three dependent variables are somewhat correlated because they measure different aspects of a human being’s capacity to intake and process information. This in turn has implications for life management i.e., an individual’s ability to cope with life experiences.
