Step Four: Calculate the Sum of SquaresFinally, you can use the sum of squares formula to calculate it by adding the squared deviation scores for each data point together. SS=∑(xi−xˉ)2SS=∑(xi−xˉ)2For example, let’s find the sum of squares for the numbers [1,3,4,5,...
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...

In a similar manner, the sum of squares for computing nsmeans2, often referred to as the “between groups” or “factor sum of squares,” can be obtained by using the formula SSB=∑Yi.2ni−Y..2∑ni, which is divided by its degrees of freedom, dfB=T−1, to obtain nsmeans2, ...
SSSS— Sum of squares; yiyi— The ith value in the sample; yˉyˉ— Mean value of the sample; and yi−yˉyi−yˉ— Deviation of each data point from the mean. To better understand the formula, let's discuss an example. Suppose you're trying to calculate the sum of squared devi...
