The total sum of squares (TSS), the explained sum of squares (ESS), the residual sum of squares (ESS), and sum of squares within (SSW) are all measures of variation in a data set. However, they measure differenttypesof variation. Formula and Example The formula for the sum of the sq...

Finally, there is no denominator in the sum of squares formula to divide by the number of observations ordegrees of freedom. That’s the unscaled nature of SS. This statistic grows with the sample size. This sum of squares formula is the starting point for other variability measures that do...
Sum of squares of numbers indicates the addition of squared numbers with respect to arithmetic operations as well as statistics. Learn the formulas here along with solved examples
Sum of Squares Formula The following is the formula for the total sum of squares. Variation is a statistical measure that is calculated or measured by using squared differences. How to Calculate the Sum of Squares You can see why the measurement is called the sum of squared deviations, or th...
The sum of squares for computing the pooled variance, often called the “within groups” or the “error sum of squares,” is simply the sum of the sums of squares for each of the samples, that is, SSW(or SSE)=∑SSi=∑i∑j(yij−y¯i)2=∑i,jyij2−∑iYi.2ni, where the...

In this article, we use combinatorial reasoning to derive a formula for the sum of the first n squares: $$1^2 + 2^2 + 3^2 + \\\cdots + n^2 .$$ Following this we do the same for the formula for the sum of the first n cubes. Then we look at the problem more generally.do...
