The harmonic mean is a type of average, often used in situations where the average of rates or ratios is needed. Unlike the arithmetic mean, the harmonic mean gives less weight to large values and more weight to small values, making it particularly useful for averaging rates and ratios.
What is Harmonic Mean?
The harmonic mean is defined as the reciprocal of the arithmetic mean of the reciprocals of a set of numbers. It is especially appropriate for situations when the average of rates is desired.
