Too many synonyms

I’m now up to five different terms for “independent variable” (X’s) in my methods lecture for today (thanks in part to a Polmeth post that just reminded me of one I’d forgotten to put on the list), and I’m probably missing some. You’d think we could narrow that down a little. The others: covariate, predictor, explanatory variable, and regressor.

Funnily enough, I only came up with “dependent variable” and “regressand” for Y, but I’m surely missing some there too.

You also missed “right-hand-side variable” for X. Y can be “outcome,” “response variable,” and “left-hand side variable.”

How do you distinguish among the right-hand-side variables? For instance, research hypothesis-variable, alternative-hypothesis-variable, and control variables?


I also missed “treatment” for X.

As for the research hypothesis variable etc, I really don’t bother, although I do talk about intervening variables when talking about additive, interactive, and spurious relationships.
