What is the average (arithmetic mean) of 8, 7, 7, 5, 3, 2, and 2?

Solution:

Given, 8, 7, 7, 5, 3, 2 and 2

We have to find the arithmetic mean for the given data.

Arithmetic mean = sum of all observations / total number of observations.

Sum of all observations = 8 + 7 + 7 + 5 + 3 + 2 + 2 = 34

Total number of observations = 7

So, arithmetic mean = 34/7

= 4.86

Therefore, the arithmetic mean is 4.86.

Example:

What is the average (arithmetic mean) of 8, 7, 5, 5 and 2?

Solution:

Given, 8, 7, 5, 5 and 2

We have to find the arithmetic mean for the given data.

Arithmetic mean = sum of all observations/total number of observations.

Sum of all observations = 8 + 7 + 5 + 5 + 2 = 27

Total number of observations = 5

So, arithmetic mean = 27/5

Therefore, the arithmetic mean is 27/5.
