formula of weighted mean

Here you will learn what is weighted mean formula and how to calculate weighted mean with examples. Let’s begin – Weighted Mean Formula If $w_1$, $w_2$, ……$w_n$ are the weights assigned to the values $x_1$, $x_2$, …..$x_n$ respectively then their weighted mean is defined as Weighted mean = \(w_1x_1 + w_2x_2 +……+ w_nx_n\over {w_1 +…….+ […]
