# How to calculate sum of squares between groups

Our next step is to insert the Sums of Squares computed above into the summary table, compute the Mean Squares by dividing each sum of squares by its respective degrees of freedom, and finally computing the F-ratios by dividing each Mean Square by the Mean Square within-groups. All of these values are shown in the Table below. The section on Multi-Factor ANOVA stated that when there are unequal sample sizes, the sum of squares total is not equal to the sum of the sums of squares for all the other sources of variation. This is because the confounded sums of squares are not apportioned to any source of variation. The sum of squares total, denoted SST, is the squared differences between the observed dependent variable and its mean. You can think of this as the dispersion of the observed variables around the mean – much like the variance in descriptive statistics . Too many pattern attempts htc2.2 - One-Way ANOVA Sums of Squares, Mean Squares, and F-test by Mark Greenwood and Katharine Banner The previous discussion showed two ways of estimating the model but still hasn't addressed how to assess evidence related to whether the observed differences in the means among the groups is "real". SS-- sum of squares total. And you could view it as really the numerator when you calculate variance. So you're just going to take the distance between each of these data points and the mean of all of these data points, square them, and just take that sum. We're not going to divide by the degree of freedom,...

The mean of the sum of squares (SS) is the variance of a set of scores, and the square root of the variance is its standard deviation. This simple calculator uses the computational formula SS = Σ X 2 - ((Σ X ) 2 / N ) - to calculate the sum of squares for a single set of scores.

Calculate the Variation Within Groups To measure the variation within groups, we find the sum of the squared deviation between scores on the exam and the group average, calculating separate measures for each group, then summing the group values. This is a sum referred to as the "within sum of squares" or WSS.
