MULTIPLE REGRESSION measures the effect a group of survey questions (called the independent variables) has on a single survey question (or an average of a group of questions), called the dependent variable.
Answer Wiki. Regression is the process of fitting an (approximated) continuous function to a set of independent data points. This is useful for approximating dependent values (y) for independent values (x) that aren't present in the data set. You can even use this regression curve to predict values of y for x's that are outside of the range of the current dataset (extrapolation).
