A Weighted Arithmetic Mean Function is an arithmetic mean where some data points contribute more than others.
- Context:
- range: Weighted Arithmetic Mean Value.
- It can range from being an Informal Weighted Arithmetic Mean Function to being a Formal Weighted Arithmetic Mean Function.

- 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. The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics.
If all the weights are equal, then the weighted mean is the same as the arithmetic mean. While weighted means generally behave in a similar fashion to arithmetic means, they do have a few counterintuitive properties, as captured for instance in Simpson's paradox.
