Frequency Index Calculator

Formula

The formula to calculate the Frequency Index (FI) is:

\[ FI = \left( \frac{N}{T} \right) \times 100 \]

Where:

Frequency Index: 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.
Significance: 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.

Let's say the number of occurrences (N) is 50 and the total number of opportunities (T) is 200. Using the formula:

\[ FI = \left( \frac{50}{200} \right) \times 100 = 25 \]

So, the Frequency Index (FI) is 25%.
