response (dependent) variables - one particular variable that we are interested in understanding or modeling (y) predicting or explanatory (independent) variables - a set of other variables that might be useful in predicting or modeling the response variable (x1, x2) What kind of variable is a response variable and why? - random, because it varies with changes in the predictor/s along with other random changes. What kind of variable is a predicting variable and why? - fixed, because it ...
