Fifteen out of 60 participants scored between 17 and 21 on a test. what is the relative frequency of the class interval 17-21?

musickatia [10]

The frequency is how often something occurs. Here 15. It occurred 15 times that the participants scored in the interval given.

The relative frequency (expressed as a percent) looks at how often something occurred relative to the overall occurrences. Here 15/60 = 1/4 = 25%

The relative frequency is 25%
