What is f in mean formula?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
In the mean formula for grouped data, f represents frequency. It shows how many times a particular value or class interval occurs in a dataset.
Frequency is essential because it weights values correctly when calculating the mean. For example, if a test score appears many times, it should influence the average more than a score that appears once. This approach is widely used in statistics, surveys, and data analysis.
