Illustration of variance, MATLAB in Mathematics

Illustration of Variance

For illustration, for the vector [4, 6, 1, 5], there are n = 4 values therefore n - 1 is 3. The mean of this data set is also 4. The variance will be

The built-in function to compute the variance is known as var:

>> shortx = [4 6 1 5];

>> myvar = var(shortx)

myvar =
