The relative frequency of a class is the fraction or proportion of the total number of data items belonging to the class. A relative frequency distribution is a tabular summary of a set of data showing the relative frequency for each class. Percent Frequency Distribution. The percent frequency of a class is the relative frequency multiplied by 100.

Characterize this distribution based upon this calculation and the relative frequency histogram made in item #8. The drying time for one of the cans of paint was 106 minutes. Relative to the mean for the sample, how many standard deviations away was this can’s drying time? (z-score formula) Determine the variability of the data (CVAR)

The graph below shows the relative frequency distribution for X , the total number of dogs and cats owned per household, for the households in a large suburban area. For instance, 14 percent of the households own 2 of those pets. (a) According to local law, each household in this area is prohibited from owning more than 3 of these pets.

Relative frequency: (frequency of a class)/n, where n is the total number of the data. Percent frequency: (relative frequency)× 100%. Based on the frequency distribution, relative frequency, and percent frequency of the data, we can use table and graphs to display these frequencies. Example:
