WebBy comparison, a "regular" average would count each assignment one time, so each one has the same weight. If you could look "under the hood" of the SUMPRODUCT function, you would see that this is what it is actually … WebWeighted average formula. The formula for computing a weighted arithmetic mean is as follows: where x i are values of the variable X, w i are the associated weights, and Σ, the Greek upper-case letter "sigma", is the symbol for the sum operation. This weighted mean equation can be expanded for easier comprehension like so:
WebHowever this one (using fractional weights) does not work for me: If each x i is drawn from a Gaussian distribution with variance 1 / w i, the unbiased estimator of a weighted population variance is given by: s 2 = V 1 V 1 2 − V 2 ∑ i = 1 N w i ( x i − μ ∗) 2.
