Enter the number of occurrences and total number of opportunities into the calculator to determine the Frequency Index. This calculator can also evaluate any of the variables given the others are known.
Frequency Index Formula
The following formula is used to calculate the Frequency Index.
FI = (N / T) * 100
Variables:
- FI is the Frequency Index
- N is the number of occurrences of an event
- T is the total number of opportunities for the event to occur
To calculate the Frequency Index, divide the number of occurrences of an event by the total number of opportunities for the event to occur. Multiply the result by 100 to convert it to a percentage. This will give you the Frequency Index, which represents the frequency of occurrence of an event relative to the total number of opportunities for the event to occur.
What is a Frequency Index?
A Frequency Index is a statistical tool used to measure the frequency or rate of occurrence of a particular event or phenomenon within a specific time period or data set. It is often used in fields such as marketing, economics, and social sciences to analyze trends, patterns, and behaviors. The index is typically expressed as a percentage or ratio, providing a clear and concise way to compare and contrast different data points or categories.
How to Calculate Frequency Index?
The following steps outline how to calculate the Frequency Index.
- First, determine the number of occurrences of an event (N).
- Next, determine the total number of opportunities for the event to occur (T).
- Next, gather the formula from above = FI = (N / T) * 100.
- Finally, calculate the Frequency Index.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Number of occurrences of an event (N) = 25
Total number of opportunities for the event to occur (T) = 100
