WebMar 10, 2024 · Here are steps you can follow to calculate the sum of squares: 1. Count the number of measurements. The letter "n" denotes the sample size, which is also the number of measurements. 2. Calculate the mean. The mean is the arithmetic average of the sample. To do this, add all the measurements and divide by the sample size, n.
