Calculating the sum of squares of x ( SSxx) is an important step in linear regressions such as the Pearson product-moment correlation coefficient or the least squares fitting technique. Sum of squares is used in statistics to describe the amount of variation in a population or sample of observations. To calculate the sum of squares of x, square the difference between each x data point and the mean of x, and then sum the squares. This is the predictor variable (also called dependent variable). Statistics: Calculate a Pearson's r. In a study on caffeine and stress, college students indicated how many cups of coffee they drink per day and their stress level on a scale of 1 to 10.
