Population Mean Formula

The ratio wherein the addition of the values to the number of the value is a population mean – if the possibilities are equal. A population mean include each element from the set of observations that can be made.

The population mean can be given in the following formula:

\[\large \mu=\frac{\sum x_i}{N}\]

Where,
$x_{i}$ = Sum of the values
N=number of the value

Solved Examples

Question: Find the population mean of the following numbers 1, 2, 3, 4, 5?

Solution:

Given,
$x_{i}$ = 1 + 2 + 3 + 4 + 5 = 15
N = 5

Population Mean = $\frac{\sum x_{i}}{N}$

$\mu$ = $\frac{15}{5}$

$\mu=3$

Population Mean = 3
