Why does Khan Academy not use the accepted formula for standard deviation? Kids can't practice correctly for the AP statistics exam with Khan Academy unless this is fixed. The accepted formula has the sum of deviations squared divided by (n-1) while Khan currently excepts answers that are divided by n.
