**Introduction to Regression Analysis**

**Overview: **Regression analysis allows for the prediction of outcomes.
Given two variables, we can predict score on one (Y) from the other (X) if we
know their linear relationship (i.e., the correlation between the variables).

**Goals**: This set of tutorials will help you understand the vocabulary,
logic, and basic mathematics of regression and correlation. Special attention
will be given to the relationship between plots and calculations, and the
influence of extreme scores on correlation/regression.

**What do I need to know? **You
should know how to interpret a scatter plot of X and Y scores. The Review of
Prerequisites covers basic concepts that will help you with the modules.
