MANOVA and MANCOVA

MANOVA is an extension of ANOVA when there are more than one dependent variable.

• True

• False

The dependent variables in MANOVA must be related in some way.

• True

• False

With two dependent variables and one independent variable, two ANOVA's can be done in order to reduce the Type I error.

• True

• False

Supposed you don't want to do a MANOVA even if the conditions are met to do the same, dividing the alpha value by the number of ANOVA tests you want to perform will result in a cut-off alpha value for statistical significant difference between your groups. This is called

• Mahalanobis Distance

• Covariate Analysis

• Bonferroni Adjustment

• Rejection Region

In which of the following conditions can MANOVA be used? Check as many as you can.

• One-Way

• Two-Way

• Many Independent Variables

• With Covariates

Are males better adjusted than females in terms of their positive and negative mood states and levels of perceived stress? What is/are the dependent variable/s in this research question?

• Gender

• Gender and Mood States

• Mood States and Levels of Perceived Stress

• Positive and Negative Mood states

In one-way MANOVA, which variable must be continuous?

• Independent Variable

• Dependent Variable

Which of the following null hypotheses is the most correct for one-way MANOVA?

• The population mean of a dependent variable does not vary across different levels of a grouping variable.

• The population means on a set of dependent variables do not vary across different levels of a grouping variable.

• The population means on a set of dependent variables vary across different levels of a grouping variable.

• The population mean of a dependent variable varies across different levels of a grouping variable.

If we have two dependent variables and 3 levels of independent variable in MANOVA, we have a total of ____ cells and the minimum sample size per cell is _____.

• 6, 2

• 5, 3

• 3, 2

• 2, 3

Multicollinearity of dependent variables in MANOVA can prevented by removing one of the strongly correlated pairs if the r between them is equal or greater than ________.

• 1
