How Do You Calculate The Harmonic Mean?
When your teacher asks you to calculate the harmonic mean, you need to know what a harmonic mean is and what factors you’ll need to complete the task. You also need to know some simple algebraic functions. Here is how to calculate the harmonic mean so you can ace that next math test. Know that a “mean” is a term that refers to the average. In the case of harmonic mean, it would be the average rate. For instance, it would be the rate of flow of a liquid over a period of time. Identify the factors that you need average. In most cases this is a word problem with several rates and times identified in the problem. Look closely for what rates the word problem reveals and the periods of time specified for each. Take the sum of the rates. Express the rates as a fraction, for example, the first hour maybe 3 gallons of flow occurred, or 1/3 for the first hour of flow, then the second hour 2 gallons of water, or 1/2 for the second hour and so on. Add all the rates to calculate a total of the rate
