How to calculate sample variance?
Short discussion of the relationships among sum of squares, variance, and standard deviation using a computational example. The standard deviation (σ) is simply the (positive) square root of the variance. In order to write the equation that defines the . And then we're dividing, not by the number of data points we have, but by 1 less than the number of data points we have.
