It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
We can consider the following set of numbers.
= 1, 2, 3, 4, 5
The mean of 1, 2, 3, 4, 5.
= (1 + 2 + 3 + 4 + 5) / 5
= 15/5
= 3
We see that,
While calculating the mean we add all the given values and divide by the number of values added.
Thus,
