A line of best fit is drawn on the scatter diagram. It is drawn so that the points are evenly distributed on either side of the line. There are various methods for drawing this 'precisely' but you ...

How to Know if This Major Is the Right Fit for You Physics students should be curious about the mathematical intricacies that underlie the universe and be prepared to work on complex problems.

The 'line of best fit' is a line that goes roughly through the middle of all the scatter points on a graph. The closer the points are to the line of best fit the stronger the correlation is.
