What the relative frequency calculator solves
Use this relative frequency calculator to count a target value and compare it with the total number of observations.
Formula
How to use it
- Enter a dataset as numbers separated by commas, spaces, or semicolons.
- Choose sample or population when the statistic uses a different denominator.
- Use the sorted data, count, mean, and work lines to check the result.
How to read the answer
Relative frequency describes the share of the dataset that matches the target value.
Common mistakes and edge cases
- Count the target value exactly unless your class tells you to group values into intervals.
- Use percent points for the displayed result, not decimal probability unless requested.
- A target that never appears has 0% relative frequency.
