variance
Computes the population variance.
variance takes the mean squared deviation from the arithmetic mean, dividing by the total number of values. Use smpvar for the sample variance with an n-1 denominator.
Both the notation function and the direct nerdamer/statistics export accept separate values or one vector.
Examples
These examples use Nerdamer Notation.
Compute an exact population variance.
variance(1,2,3)
