If the researchers want to be a little more accurate and reduce the chances of differences between the groups having an effect, they use modifications of the design. For example, maybe one class had a great teacher and has always been much more motivated than the others, a factor that would undermine the validity of the experiment.

Key Points. One use of multiple regression is prediction or estimation of an unknown Y Y value corresponding to a set of X X values. A second use of multiple regression is to try to understand the functional relationships between the dependent and independent variables, to try to see what might be causing the variation in the dependent variable.
