Weighted mean = Σwx/Σw. Σ = summation (in other words…add them up!). w = the weights. x = the value. To use the formula: Multiply the numbers in your data set by the weights. Add the numbers in Step 1 up. Set this number aside for a moment. Add up all of the weights.
He can calculate the weighted mean for the average share price. In this example, the prices are the values, and the numbers of stocks are the weights. Here, the weights sum to 125. Consequently, we need to divide the sum of the products (2,985) by 125. The weighted average price per stock is $23.88.

Uses of Weighted Means. Weighted means are useful in a wide variety of scenarios. For example, a student may use a weighted mean in order to calculate his/her percentage grade in a course. In such an example, the student would multiply the weighing of all assessment items in the course (e.g., assignments, exams, projects, etc.) by the ...
Weighted Mean: A mean where some values contribute more than others. When the weights add to 1: just multiply each weight by the matching value and sum it all up. Otherwise, multiply each weight w by its matching value x, sum that all up, and divide by the sum of weights: Weighted Mean = Σwx Σw.
4 days ago · In Mathematics, the weighted mean is used to calculate the average value of the data. In the weighted mean calculation, the average value can be calculated by providing different weights to some of the individual values. We need to calculate the weighted mean when data is given in a different way compared to the arithmetic mean or sample mean.

A weighted average (or weighted arithmetic mean) is an average of a data set in which certain data points carry more weight; in other words, certain data points contribute more to the final average of the data set. Normally, when computing an average, each data point carries the same weight. For example, the average of the set {1, 3, 7, 10, 15} is:
