Regression Equation . Now that we know how the relative relationship between the two variables is calculated, we can develop a regression equation to forecast or predict the variable we desire.

With a correlation that low, there will be some mean regression at work. Think of it this way. Seven door-to-door salesmen go out and sell as many vacuum cleaners as they can on a Sunday.

Because the correlation is less than one, regression to the mean occurs. This suggests that although tall parents usually have tall children, their children will likely be shorter than them and ...

In my opinion, reversion to the mean is one of the most powerful, but least understood, concepts in statistics. Regression to the mean explains that in many cases data will tend to even out—i.e ...
