Enter the population variance and the population mean into the calculator to determine the maximum and minimum usual values.

## Maximum Usual Value Formula

The following formula is used to calculate a maximum usual value.

MUV = μ + 2*σ

• Where MUV is the maximum usual value
• μ is the population mean
• σ is the population variance

To calculate the maximum usual value add two times the population variance to the population mean.

Similarly, to calculate the minimum usual value, subtract two times the variance from the mean.

## What is a maximum usual value?

Definition:

A maximum usual is a measure of the maximum value that the data or a population usually falls below. It is equal to the mean plus two times the variance.

## How to calculate maximum usual value?

Example Problem:

The following example outlines how to calculate a maximum usual value.

First, determine the population mean. In this example, the population mean is measured to be 100.

Next, determine the population standard deviation. In this case, this is calculated to be 5.6.

Finally, calculate the maximum usual value using the formula above:

MUV = μ + 2*σ

MUV = 100 + 2*5.6

MUV = 111.2
