What is the sum of a square. The Total Sum of Squares is a measurement of the dependent variables variation. It is defined as being the sum over all observations of the squared differences of each observation from the overall mean. Sum of squares theorems give formulaic ways to differentiate which numbers can and cannot be expressed as sums of squares.
Before knowing what is the sum of the perfect squares formula first let us recall what are perfect squares. It could be finding the sum of squares of 2 numbers or 3 numbers or sum of squares of consecutive n numbers or n even numbers or n odd numbers. It is basically the addition of squared numbers.
