Line of Best Fit via Least Squares (Tanton Mathematics)

Have you ever wondered in fitting a line to data on a scatter plot that you work to minimise the vertical distances of points from the line - not the actual distances (perpendicular to the line)? Or why you square numbers rather than work with the natural thing which would be absolute value? In this video I explain why we calculate the line of best fit the way we do, and explain the mathematics behind the formula for the best line. It really isn't that bad!
