What is Harmonic Mean?
Harmonic mean is a measure of central tendency. Say we want to determine a single value that can be used the describe the behavior of data around a central value. Then such a value is known as a measure of central tendency. In statistics, there are three measures of central tendency. These are the mean, median, and mode. The mean can be further classified into arithmetic mean, geometric mean, and harmonic mean.
