Predictor Variable. A continuous predictor variable is sometimes called a covariate and a categorical predictor variable is sometimes called a factor. The variables that have a relationship with the predicted variable are called independent or predictor variables.
Lets say you run an experiment investigating the amount that people like you after you give them money. In the example we just used now Mia is using attendance as a means to predict another variable. The Moderator Z is the predictor that changes the effect of the Independent Variable X on Y.

Predictor variable also known sometimes as the independent variable is used to make a prediction for dependent variables. Predictor variables are also known as independent variables x-variables and input variables. Response Variable When using regression the response variable is the variable we attempt to predict and the predictor variable is what we use to predict the response variable. The notation for a raw score regression equation to predict the score on a quantitative Y outcome variable from scores on two X variables is as follows.
