Question

Find the mean of the first $10$ whole numbers?

Answer 1

Compute the required mean:

Since, $0,1,2,3,4,5,6,7,8,9$ are the first ten whole numbers.

We know that the formula of the mean can be given as:

$\text{Mean=}\frac{\text{Sum of all the observations}}{\text{Total number of observations}}$

Compute the required mean as follows:

$Mean=\frac{0+1+2+3+4+5+6+7+8+9}{10}=\frac{45}{10}=4.5$

Hence, the mean is $4.5$.
