+1.5+.75+.5+.25)/5 = 0.65. * **Weighted Average:** (0.25*1.5 + 0.25*0.75 + 0.25*0.5 + 0.25*0.25) / (0.25+0.25+0.25+0.25) = (0.375 + 0.1875 + 0.125 + 0.0625) / 1 = 0.75. (Assuming equal weights for simplicity, but the point is how weights would apply)So, in general, to calculate a weighted average of values $x_1, x_2, dots, x_n$ with corresponding weights $w_1, w_2, dots, w_n$, the formula is:$$ text{Weighted Average} = frac{sum_{i=1}^{n} w_i x_i}{sum_{i=1}^{n} w_i} $$In the context of the prompt, the values are likely the individual data points, and the weights would represent their relative importance or frequency.—Let’s consider the phrase “weighted average sum”. This is unusual. An average is a sum divided by a count (or sum of weights). A sum is just adding things up.If the user literally means “weighted average sum”, it
