For the special case of just two numbers and the harmonic mean can be written. Determine the values you need to find the harmonic mean for. This can be any set of numbers.
Determine the values you need to find the harmonic mean for.
The difference between these two is that the first problem is calculating an average speed based on time while the second is based on distance. Plug the value of n. Harmonic mean is used when average of rates is required below is the formula. Where n is the total number of values and x i x 2 x 1.
