The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others.
Learn how to calculate a weighted average, a type of mean that gives differing importance to the values in a dataset. See two examples with weights that sum to one and to a different value.
Learn how to calculate the weighted mean of a set of data with different weights. See the formula, the properties and a solved example of weighted mean in statistics.
Learn how to calculate a weighted mean, a mean where some values contribute more than others. See how to use weights for decisions, ratings and averages with examples and a formula.
A weighted mean is a kind of average. Instead of each data point contributing equally to the final mean, some data points contribute more “weight” than others. If all the weights are equal, then the weighted mean equals the arithmetic mean (the regular “average” you’re used to).
Learn how to calculate the weighted mean of a set of data with different weights. The weighted mean is the sum of the products of weights and quantities, divided by the sum of weights. See examples, formula and comparison with arithmetic mean.
Learn what a weighted average is, how to calculate it, and why it is useful. See examples of weighted averages in education, statistics, and manufacturing.
