Statistics.harmonic mean?

The harmonic mean is a measure of how many people you need to feed to have the same average population. It is a compromise between the arithmetic mean, sum of the values divided by the number of items, and the geometric mean, which is their average raised to the power of 0.5. The harmonic mean is simply the sum of the reciprocals of the number of items.

What is the statistical mean of the harmonic mean?

The harmonic mean is a measure of central tendency, or the typical value of a set of data. If you have a group of 20 people, take the average of their ages. The average of the 20 ages is the statistical mean of the ages. The same is true for the sum of the 20 ages. The sum of the 20 ages is equal to the total number of people multiplied by their average age. The harmonic mean of the 20 ages is the 20th root of the product of the sum

What is the mean of the harmonic mean in statistics?

The harmonic mean is a statistical measure used in composite scores, which is a combination of several different scores, each on different questions. A simple example of a composite score is the number of hours you spent on homework each week. Using the arithmetic mean, you could add up the number of hours you spent on homework every week, and divide the total by how many weeks you did. However, because you may have gotten better at your homework over time, your mean score may be skewed. To remedy this

What is the mean of the harmonic mean?

The harmonic mean is the reciprocal of the arithmetic mean of a set of values. If you take the average of values 1, 2, and 3, the harmonic mean is 1/1+1/2+1/3. The geometric mean is the square root of the product of the values. If you take the average of values 1, 2, and 3, the geometric mean is 1√1+1√2+1√3 ≈ 1.5.

What is the meaning of the mean of the harmonic mean?

The harmonic mean is the reciprocal of the arithmetic mean of each value raised to the power of its rank. That is, the harmonic mean of a set of numbers is equal to the number obtained by raising the numbers in the set to the sum of their ranks and then taking the reciprocal of that product.
