## Regression Analysis 1

- If two variables are correlated, you can create an equation that will predict one of the variables if the other is known.
- This equation is known as a
*regression analysis* because it estimates the point that a score will fall on a regression line.
- Regression analysis assumes that there is a relationship between two variables and that this relationship can be represented as a straight line.
- Therefore if we know where X falls on this line, we can use the regression equation to predict where Y could fall on this same line.
