Comparing MANOVA to Multiple ANOVAs

In this assignment, you will discuss the problems associated with conducting multiple univariate ANOVA when compared to conducting a single MANOVA. Researchers are often faced with research situations that require testing multiple DVs. Just as conducting multiple t-tests is problematic when we have an independent variable with more than two levels, so too is conducting multiple ANOVAs when we have more than one DV. This is particularly true if the DVs are correlated with one another. For this discussion:

In a minimum of 200 words, respond to the following:

• Discuss the disadvantages of using multiple ANOVAs to test the results on multiple DVs when compared to a MANOVA.
• Discuss the disadvantages of using a MANOVA instead of conducting multiple ANOVAs to analyze the results of multiple DVs.
• Describe a hypothesis that would require the use of a MANOVA to analyze results.
