1
The Median-Median Line

2
Process zSort the collected data by the independent variable. zDivide the sorted data into three groups. zFind the median x and the median y of each group. zFind the equation of the line that passes through (x1, y1) and (x3, y3).

3
Process zFind the equation of the line parallel to the previous line that passes through (x2, y2). zFind the weighted average of the y-intercepts. b=(b1+b2+b1)/3 zThe median-median line is the line parallel to the previous two lines with the weighted y-intercept.
