How do you find the sum of squares and variance?
The sum of squares is all the squared differences added together. S S = ∑ i = 1 n ( x i − x ¯) 2. Calculate the variance. Variance is the sum of squares divided by the number of data points. The formula for variance for a population is: Variance = σ 2 = Σ ( x i − μ) 2 n.
