One important application is determining the coefficient of determination (R2), which indicates the ratio of the explained sum of squares to the total sum of squares. 5. Sum of Squares Within Within-group variation is reported inANOVAoutput as SS(W) or which means Sum of Squares Within groups...
How to Calculate R-Squared The formula for calculating R-squared is: Where: SSregressionis the sum of squares due to regression (explained sum of squares) SStotalis the total sum of squares Although the names “sum of squares due to regression” and “total sum of squares” may seem confus...
How to Calculate the Total Sum of Squares Within and Between (SSW and SSB) Step 1: For each group of data, calculate the mean. Step 2: Subtract the group mean from each data point that belongs to that group for all data points. Square and sum all these differences to...
Finding the Sum of Squares for Just a Few Cells Finding the sum of squares in Microsoft Excel can be a repetitive task. The most obvious formula requires a lot of data entry, though there's a lesser-known option that gets you to the same place. ...
The residual sum of squares (RSS) is a statistical technique used to measure the variance in a data set that is not explained by the regression model.
The variance is usually calculated automatically by whichever software you use for your statistical analysis. But you can also calculate it by hand to better understand how the formula works. There are five main steps for finding the variance by hand. We’ll use a small data set of 6 scores...

This FAQ demonstrates how to calculate least-squares means in Stata. A least-squares mean is a population mean that is calculated using parameter estimates from a statistical model. But where does the name “least-squares mean” come from? The first use of the expression “least-squares mean...
The results from a Two Way ANOVA will calculate a main effect and an interaction effect. The main effect is similar to a One Way ANOVA: each factor’s effect is considered separately. With the interaction effect, all factors are considered at the same time. Interaction effects between factors...
