When a weighted mean is used, the variance of the weighted sample is different from the variance of the unweighted sample. The biased weighted sample variance is defined similarly to the normal biased sample variance: where, which is 1 for normalized weights.or example, consider the weighted mean of the point [1 0] with high variance in the second component and [0 1] with high variance in the first component.
