Account for more variance in multivariate models
The way to "control for" a variable is to enter it into a multivariate model with other independent and dependent variables of interest. Control variables are chosen because the researcher has an informed hypothesis that the control variable is important when understanding treatment effects and needs to be accounted for in a multivariate analysis.
