This virtual manipulative enables students to construct scatterplots to visualize the relationship between two variables. Students click on a point on a grid to enter data. The manipulative displays a red regression line that approximates the set of indicated points. A yellow dot indicates the mean value for the data. The number of points, the average x and y values, the correlation coefficient, and the equation for the regression line appear on the screen. Instructions for using the manipulative, a suggested activity, a lesson plan, and a link to the National Council of Teachers of Mathematics (NCTM) standard for data analysis and probability are included.
