What is Harmonic mean?
The harmonic mean can be defined as:
Harmonic mean is one of the Pythagorean means, the three important central tendencies. It has its uses in physics, geometry, stats, and finance.
Harmonic mean formula:
The formula used for the calculation of harmonic mean is given below.
In this equation:
- n is the number of entries.
- x1 is the first entry.
- xn is the last entry.
The harmonic mean formula of 2 and 3 values is further simplified to make the process easy.
For 2 values, H.M = 2 * x * y / (x + y)
For 3 values, H.M = 3 * x * y * z / (x + y +z)
Calculating H.M using G.M and A.M
If you have the arithmetic mean and geometric mean of n values, then you can easily calculate the harmonic mean by this formula:
H.M = G.M2 / A.M
How to calculate the harmonic mean?
To find the harmonic mean:
- Count the values.
- Find the reciprocal of each number or reading.
- Add all of the reciprocals.
- Divide the total number of values (n) by the sum of the reciprocals.
For the given set of data, find the harmonic mean.
(1, 17, 7, 41, 2)
Step 1: Count the number of values.
There are 5 values.
Step 2: Find the reciprocal of each value.
1/1 = 1
1/17 = 0.0058
1/7 = 0.1429
1/41 = 0.0244
1/2 = 0.5
Step 3: Add all reciprocals.
= 1 + 0.0058 + 0.4129 + 0.0244 + 0.5
Step 4: Divide the total number of values by this sum.
= 5 / 1.7261
If the G.M of a set of data is 2√3 and A.M is 6. Then find its harmonic mean.
Step 1: Identify the given data.
A.M = 6
G.M = 2√3
Step 2: Use this data in the formula.
H.M = G.M2 / A.M
H.M = (2√3)2 / 6
H.M = (4*3) / 6
H.M = 12 / 6
H.M = 2
