In mathematics the harmonic series is the divergent infinite series. Math explained in easy language plus puzzles games quizzes videos and worksheets. If n is the number of numbers it is found by dividing the number of numbers by the reciprocal of each number.
Yes that is a lot of reciprocals. Find the harmonic mean of the set of numbers 2 4 1 and 3. Its name derives from the concept of overtones or harmonics in music.
Calculating weighted harmonic mean is similar to the simple harmonic mean. X n also called subcontrary mean is given by the formula below. Illustrated definition of harmonic mean.
In mathematics the harmonic mean sometimes called the subcontrary mean is one of several kinds of average and in particular one of the pythagorean meanstypically it is appropriate for situations when the average of rates is desired. The other two are arithmetic mean and geometric meanit is a type of average which is calculated by dividing the number of values by the sum of reciprocals of each value. The harmonic mean can be expressed as the reciprocal of the arithmetic mean of the reciprocals of the given set of observations.
