Relative Frequency is How often something happens divided by all outcomes.
To compute relative frequency, one obtains a frequency count for a subgroup of the population and a frequency count for the total population. The relative frequency is:
How to Find Relative Frequency
Relative frequency = Subgroup count / Total count
The above equation expresses relative frequency as a proportion. You can also express it as a percentage. For example, a relative frequency of 1/5 is equivalent to a percentage of 20%.
Examples
1. You has won 3 games from a total of 4 games played| Count | Relative frequency | |
| Win | 3 | 3/4 = 75% |
| Lose | 1 | 1/4 = 15% |
| Count | Relative frequency | |
| MacBook | 10 | 10/100 = 10% |
| ASUS | 20 | 20/100 = 20% |
| MSI | 30 | 30/100 = 30% |
| ACER | 40 | 40/100 = 40% |
| TOTAL | 100 | 100/100 = 100% = 1 |
All the Relative Frequencies add up to 1 (except for any rounding error).
