Following is the list of statistics formulas used in the Tutorialspoint statistics tutorials. Each formula is linked to a web page that describe how to use the formula.AAdjusted R-Squared - R2adj=1−[(1−R2)(n−1)n−k−1]Radj2=1−[(1−R2)(n−1)n−k−1] ...
In statistics, the residual sum of squares (RSS), also known as the sum of squared residuals (SSR) or the sum of squared errors of prediction (SSE), is the sum of the squares of residuals (deviations of predicted from actual empirical values of data). ...
The variance is the measure of the variability from the mean in a data set. The variance is equal to the standard deviation squared. s2=∑(xi−xˉ)2n−1s2=n−1∑(xi−xˉ)2Where: x̄ = sample mean xi = each number in the set n = number of items in the sample ...

In ANOVA, Total SS is related to the total sum and explained sum with the following formula: Total SS = Explained SS + Residual Sum of Squares. The sum of squares can also be used to calculate other statistical measures, such as thecoefficient of determinationand themean squared error. ...
In statistical data analysis the total sum of squares (TSS or SST) is a quantity that appears as part of a standard way of presenting results of such analyses. It is defined as being the sum, over all observations, of the squared differences of each observation from the overall mean. ...
Add up all of the squared values. Divide this sum of squares by n – 1 (for a sample) or N (for the total population). What Is Variance Used for? Variance measures the degree of spread in a data set from its mean value. It shows the amount of variation that exists among the data...
