Drag a line of best fit until the residual bars balance, tap the outlier, slide a marker up the line to predict, and dial relative frequencies from a two-way table.
Two handles pin a line across a scatter plot; dragging them tilts and lifts it while a residual bar hangs from every point, and the line is accepted when it is as good as the least-squares fit, with misses saying where the points sit relative to the line rather than giving an arrow. Other modes have the player tap the outlier that breaks a trend, slide a marker up a given x until it sits on the fitted line (or compute y from the shown equation), and dial a row or column relative frequency from a two-way table as a percent. It targets the slips of fitting a line through the first and last points and of dividing by the grand total instead of the group. Best for Grades 7–8.
