WebThe weighted arithmetic mean is a measure of central tendency of a set of quantitative observations when not all the observations have the same importance.. We must assign a weight to each observation depending on its importance relative to other observations. The weighted arithmetic mean equals the sum of observations multiplied by their weights … 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.

WebNov 14, 2024 · Harmonic Mean is a form of numerical average. It is computed by dividing the total number of observations by the reciprocal of each number in the series. As a result, harmonic mean is the reciprocal of the arithmetic mean of reciprocals. A central tendency measure is a single number that describes how a set of data clusters around a core value.
WebThe arithmetic mean is a measure of central tendency.It allows us to characterize the center of the frequency distribution of a quantitative variable by considering all of the observations with the same weight afforded to each (in contrast to the weighted arithmetic mean)..
