When evaluating the effectiveness of an intervention, it would be appropriate to conduct a multiple analysis of variance (MANOVA) when:
A)There is more than one dependent variable.
B)We want to avoid inflating the probability of a Type 1 error.
C)The dependent variables being used are correlated with one another in such a way that an intervention will not have significant effects on any one of them alone, but will have a significant effect on a linear combination of them.
D)All of these are reasons for conducting a MANOVA.

A MANOVA is appropriate when there is more than one dependent variable, when we want to avoid inflating the probability of a Type 1 error, and when the dependent variables are correlated with one another in such a way that an intervention will not have significant effects on any one of them alone, but will have a significant effect on a linear combination of them. Therefore, all of these are valid reasons for conducting a MANOVA.
