multivariate test

any of various statistical procedures involving two or more outcome or dependent variables. An example is the multivariate analysis of variance, which extends the analysis of variance examining one dependent variable to include additional dependent variables. Factor analysis and multiple regression sometimes are considered multivariate tests as well, even though the former involves a single set of variables that are not necessarily independent or dependent and the latter allows for multiple independent variables but only one outcome.
