In statistics, a weighted median of a sample is the 50% weighted percentile. It was first proposed by F. Y. Edgeworth in 1888. Like the median, it is useful as an estimator of central tendency, robust against outliers. It allows for non-uniform statistical weights related to, e.g., varying precision measurements in the sample. (Wikipedia).
Statistics - Find the weighted mean
This video covers how to find the weighted mean for a set of data. Remember that each data point is multiplied by a given weight, and then divided by the total weight. for more videos visit http://mysecretmathtutor.com
