A weighted average, or weighted mean, is an average in which some data points count more heavily than others, in that they are given more weight in the calculation. Arithmetic Mean. For example, the arithmetic mean of $${\displaystyle 3}$$ and $${\displaystyle 5}$$ is $${\displaystyle {\frac {(3+5)}{2}}=4}$$, or equivalently $${\displaystyle \left({\frac {1}{2}}\cdot 3\right)+\left({\frac {1}{2}}\cdot 5\right)=4}$$. Please submit your feedback or enquiries via our Feedback page. In contrast, a weighted mean in which the first number receives, for example, twice as much weight as the second (perhaps because it is assumed to appear twice as often in the general population from which these numbers were sampled) would be calculated as $${\displaystyle \left({\frac {2}{3}}\cdot 3\right)+\left({\frac {1}{3}}\cdot 5\right)={\frac {11}{3}}}$$. The average of four numbers is 15. The arithmetic mean (sometimes called the "unweighted average" or "equally weighted average") can be interpreted as a special case of a weighted average in which all the weights are equal to each other (equal to $${\displaystyle {\frac {1}{2}}}$$ in the above example, and equal to $${\displaystyle {\frac {1}{n}}}$$ in a situation with $${\displaystyle n}$$ numbers being averaged).
