Three levels of a treatment variable were evaluated for males and females on three dependent variables. a significant f is reported for the interaction of treatment and gender on a linear composite of the three dependent variables. which statistical analysis was used?

The correct answer is MANOVA

Explanation:

MANOVA takes into account more than one dependent variable.  This statistical analysis compares whether or not the newly created combination differs by the different groups, or levels, of the independent variable.  MANOVA assumes that the observations are independent of one another, there isn't any pattern for the selection of the sample, and that the sample is completely random.
