Explain the Sum of Squares? Why is it important?

What will be an ideal response?


The Sum of Squares is the total squared distance of all cases from the mean. The Sum of Squares is used to calculate the variance and standard deviation. The difference between each case (X) and the mean (ยต) needs to be squared in order to make the distance for each case positive. By summing these squared distances, the average distance from the mean can be calculated.
