Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sum of squares is a concept that permeates much of inferential statistics and descriptive statistics. More properly, it is the sum of the squared deviations". Mathematically, it is an unscaled, or unadjusted measure of dispersion (also called variability). When scaled for the number of degrees of freedom, it estimates the variance, or spread of the observations about their mean value. When more data is added to the collection the sum of squares will increase, except in unlikely cases such as the new data being equal to the mean. So usually, the sum of squares will grow with the size of the data collection. That is a manifestation of the fact that it is unscaled."
