Sum of Squares Calculator Thesum of squares, or sum of squared deviation scores, is a key measure of the variability of a set of data. The mean of the sum of squares (SS) is thevarianceof a set of scores, and the square root of the variance is itsstandard deviation....
squares is a very useful one, which appears almost everywhere in Statistics, but people do not often take the time to explain what it is. So, starting from the beginning, the sum of squares usually refers to the sum of squared deviations with respect to the mean, for a sample of data....

Why do we need SST, SSR, and SSE? We can use them to calculate theR-squared, conduct F-tests in regression analysis, and combine them with other goodness-of-fit measures to evaluate regression models. Ourlinear regression calculatorautomatically generates the SSE, SST, SSR, and other relevant...
