Understanding sums of squares - Minitab
support.minitab.com › en-us › minitabIn analysis of variance (ANOVA), the total sum of squares helps express the total variation that can be attributed to various factors. For example, you do an experiment to test the effectiveness of three laundry detergents. The total sum of squares = treatment sum of squares (SST) + sum of squares of the residual error (SSE)
How to compute the sum of squares in ANOVA
statkat.com › compute-sum-of-squares-ANOVAGrand mean = (23+25+18+ 29+19+21+35 +17)/8 = 23.375 ( 23 + 25 + 18 + 29 + 19 + 21 + 35 + 17) / 8 = 23.375. Sum of squares within (SSW): For each subject, compute the difference between its score and its group mean. You thus have to compute each of the group means, and compute the difference between each of the scores and the group mean to which that score belongs.
