A weighted mean is a measure of central tendency that gives more weight to data points with higher values. The weighted mean takes into account the relative importance of each value and assigns each one a weight.
Weighted means are often used when different data sets vary in terms of their respective contributions to the overall statistic or when researchers want to give more weight to certain variables than others.
