In statistics, the harmonic mean is the reciprocal of the average of reciprocals. Visit BYJU’S to learn the harmonic mean formula, weighted H.M uses and solved examples.
In mathematics, the harmonic mean is one of several kinds of average, and in particular, one of the Pythagorean means. It is sometimes appropriate for situations when the average rate is desired. The harmonic mean can be expressed as the reciprocal of the arithmetic mean of the reciprocals of the given set of observations. As a simple example ...
The harmonic mean is a numerical mean and is a measure of central tendency. It is useful in calculating the average of rates and ratios. Understand harmonic mean along with its formula and solved examples.
What is Harmonic Mean? Harmonic mean is a type of average that is calculated by dividing the number of values in a data series by the sum of the reciprocals (1/x_i) of each value in the data series. A harmonic mean is one of the three Pythagorean means (the other two are arithmetic mean and geometric mean). The harmonic mean always shows the ...
4 days ago · The harmonic mean is a numerical average calculated by dividing the number of observations, or entries in the series, by the reciprocal of each number in the series. Thus, the...

The harmonic mean is: the reciprocal of the average of the reciprocals. Yes, that is a lot of reciprocals! Reciprocal just means 1value. The formula is: Where a, b, c, ... are the values, and n is how many values. Steps: Calculate the reciprocal (1/value) for every value. Find the average of those reciprocals (just add them and divide by how ...
