multiple regression
a statistical technique for examining the linear relationship between a continuous dependent variable and a set of two or more independent variables. It is often used to predict a single outcome variable from a set of predictor variables. For example, an educational psychology researcher could use multiple regression to predict college achievement (e.g., grade point average) from the variables of high school grade point average, Scholastic Assessment Test (SAT) reading score, SAT mathematics score, and SAT writing score. When a single predictor and a single outcome are involved the process is known as linear regression. Also called multiple linear regression.
