Core Mathematics - The three-median regression line

The three-median regression line

Another regression line that can be fitted to a set of data is the
three-median regression line.

The three-median regression line involves dividing a data set into three
groups (left, middle and right) and finding the median x and y values of
each group.

These are called_ summary points._

Left (xL,yL)

Middle (xM,yM)

Right (xR,yR)
