Relative Frequency Formula
Relative Frequency = f / n
Percentage = (f / n) × 100%
Where f is frequency of the value and n is total number of observations.
⚠Relative frequencies always sum to 1.0 (or 100% for percentages), representing the entire dataset.
What is Relative Frequency?
Relative frequency is the proportion or percentage of times a particular value appears in a dataset. It's calculated by dividing the frequency of a value by the total number of observations.
Proportion
Relative frequency as decimal between 0 and 1
Percentage
Relative frequency multiplied by 100%
Comparison
Allows comparison across different dataset sizes
Distribution
Shows how data is distributed across categories
💡 Example: Data [A,B,A,C,B,A,D,C,B,A], n=10. A appears 4 times, relative frequency = 4/10 = 0.4 (40%).
