When there is a relationship between two variables, quite often it's a linear relationship, and your scatter plot will be similar to Example Plot 1, where it appears the … The best fit line is defined as the line that has a mean error of zero. If it must be a "line" we could use polyfit, which will fit a polynomial. Of course, a "line" can be defined as first degree polynomial, but first degree polynomials have some properties that make it easy to deal with. crayton flooring
