Enter the frequency of the mode (# of cases) and the total number of cases into the Variation Ratio Calculator. The calculator will evaluate and display the Variation Ratio.

## Variation Ratio Formula

The following formula is used to calculate the Variation Ratio.

v = 1- (f/N)
• Where v is the Variation Ratio
• f is the frequency of the mode (# of cases)
• N is the total number of cases

To calculate the variation ratio, subtract the result of the frequency divided by the total number of cases from 1.

## How to Calculate Variation Ratio?

The following example problems outline how to calculate Variation Ratio.

Example Problem #1:

1. First, determine the frequency of the mode (# of cases).
• The frequency of the mode (# of cases) is given as: .55.
2. Next, determine the total number of cases.
• The total number of cases is provided as: 1.
3. Finally, calculate the Variation Ratio using the equation above:

v = 1- (f/N)

The values given above are inserted into the equation below and the solution is calculated:

v = 1- (.55/1) = ( .45 )

Example Problem #2:

For this problem, the variables required are provided below:

frequency of the mode (# of cases) = 60

total number of cases = 100
