This Regression interactive also includes:

How good is the fit? Using an interactive, classmates create a scatter plot of bivariate data and fit their own lines of best fit. The applet allows pupils to display the regression line along with the correlation coefficient. As a final check, learners can judge the fitness of the lines using residuals.
