Question

Find arthmatic mean , Geometric mean , harmonic mean of two numbers 2 and 8
​

Answer 1

arithmetic mean of the observations is

AM=(2+8)/2 = 5

Harmonic mean of the observations is

HM=2/(1/2+1/8)= 16/5=3.2

Geometric mean of the observations is

GM=√(2×8)=4

Answer 2

Answer:

4 is the geometric mean because,

For example, the geometric mean calculation can be easily understood with simple numbers, such as 2 and 8. If you multiply 2 and 8, then take the square root (the ½ power since there are only 2 numbers), the answer is 4.

Arithmetic mean is 5

3.2 is the Harmonic mean
