Explanation:
Detailed explanation-1: -The sum of squares measures the deviation of data points away from the mean value. A higher sum of squares indicates higher variability while a lower result indicates low variability from the mean. To calculate the sum of squares, subtract the data points from the mean, square the differences, and add them together.
Detailed explanation-2: -What is sum of squares? The sum of squares represents a measure of variation or deviation from the mean. It is calculated as a summation of the squares of the differences from the mean. The calculation of the total sum of squares considers both the sum of squares from the factors and from randomness or error.
