Harmonic Mean
Harmonic mean is the reciprocal of arithmetic mean of reciprocal.
Formula:
Properties:
- Harmonic mean is always smaller compared to geometric mean , arithmetic mean or quadratic mean .
- To get the correct result, the data values must be all positive
Example:
Example applications of Harmonic Means:
- In traffic flow theory , time-mean-speed is an arithmetic mean of speed, while space-mean-speed is a harmonic mean of speed.The speed is measured on the same length of distance travelled.
- In Industrial Engineering, Brown Gibson method uses harmonic means to compute the performance measure of objective factors.
-
In Electrical engineering, harmonic means is applied to study the
performance of transmission communication systems with relays
Use the interactive program below to compute Harmonic mean of a list of numbers separated by comma. You may change with your own input values.
