Relative frequency and percentage
Relative frequency and percentage
- The relative frequency of a value = its frequency ÷ the total of all frequencies.
- To find the percentage, multiply the relative frequency by 100.
- For example, if there are 12 students and 4 of them got the same score, the relative frequency is 4 ÷ 12 = 1/3, and the percentage is 1/3 × 100 ≈ 33.3%.
- The total of the frequencies must equal the total number of data values. This is the most important check on a frequency table.
