## 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:

- First, determine the frequency of the mode (# of cases).
- The frequency of the mode (# of cases) is given as: .55.

- Next, determine the total number of cases.
- The total number of cases is provided as: 1.

- 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

Test your knowledge using the equation and check your answer with the calculator above.

v = 1- (f/N)** = ?**
