A frequency distribution shows the number of elements in a data set that belong to each class. For example, the following table shows the frequency distribution of gas prices at 20 different stations.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\nFrequency Distribution of Prices for 20 Gas Stations\n
Gas Prices ($/Gallon)	Number of Gas Stations
$3.50$3.74	6
$3.75$3.99	4
$4.00$4.24	5
$4.25$4.49	5

Based on this information, you can use the relative frequency formula to create the next table, which shows the relative frequency of the prices in each class, as both a fraction and a percentage. How to find relative frequency with lower class limit Roughly 25 percent of the gas stations in each state charge a price between $3.00 and $3.49; about 50 percent charge a price between $3.50 and $3.99; and about 25 percent charge a price between $4.00 and $4.49.
