Webb17 sep. 2012 · Weighted arithmetic mean allows a lack in one element to be compensated by other elements, but weighted geometric mean better reflects a situation when a shortage in one element limits the result and cannot be compensated by other elements. WebbWeighting is used to control for non-independence or to standardize the data to a population of interest when the data are not obtained via SRS. Weighting can control for correlated data (family / twin studies) or confounding (inverse probability or propensity score weighting) or missing data and or stratified sampling (Horvitz Thompson Estimator).
