This means that individuals score closer to the average as they retest. - The regression *fallacy* is contributing this to something other than chance error. +### R.M.S Error for Regression +The distance of an individual point from the regression line. +- If a point is below the line, the error is negative. +- If a point is above the line, the error is positive. +- This value is calculated by subtracting the y value of the regression line from the y value of the point. + --- # Terminology
