text: In statistical mathematics, the gradient of the least-squares regression line of best fit for a given distribution of data which is linear, numerical, and free of outliers, may be written as m = r s y s x {\displaystyle m={\frac {rs_{y}}{s_{x}}}} , where m {\displaystyle m} is defined as the statistical gradient for the line of best fit ( y = m x + c {\displaystyle y=mx+c} ), r {\displaystyle r} is Pearson's correlation coefficient, s y {\displaystyle s_{y}}
