You can transform the X and Y axes by clicking on the appropriate radio button.and select a different data set from the
pop-up menu.You also get the regression line  and correlation by entering your own data.

Components of r  ****
Shows a scatterplot of data from a bivariate distribution in which the relationship between the two variables is linear.

Reliability and Regression Analysis  ****
Allows you to examine the effects of the reliability of X and Y on  a  number of the components of the regression analysis.

Regression to the mean  ***
Show the characteristics of a group selected on the basis of  test scores.
