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. By converting this data into a relative frequency distribution, the comparison is greatly simplified, as seen in the final table.

A group of 100 students was surveyed about their interest in a new International Studies program. For a relative frequency distribution, relative frequency is computed as the class frequency divided by the number of observations. Recall that frequency is the absolute number of times that an event occurs in a sample. Construct the frequency table ( including the value / class , frequency , relative frequency and cumulative relative frequency ) for the following data , and graph a pie chart as well as a histogram or bar graph for it .

For qualitative data, the relative frequency for a class is computed as It turns out that 50 of these supermarkets charge a price between $8.00 and $8.99 for a pound of coffee. 292 A "random survey" was conducted of 3,274 people of the "microprocessor generation" (people born since 1971, the year the microprocessor was invented). b. cumulative c. a histogram Example: Cumulative frequency distribution From this table, the sociologist can make observations such as 13 respondents (65%) were under 39 years old, and 16 respondents (80%) were under 49 years old. Optional: If you want to calculate the cumulative relative frequency, add another column and divide each cumulative frequency by the sample size. Many times in statistics it is necessary to see if a set of data values is approximately normally distributed. D. Percent of observations in the class, A group of 100 students was surveyed about their interest in a new International Studies program. In a relative frequency distribution, the value assigned to each class is the proportion of the total data set that belongs in the class. b. remains unchanged The percentage of students working 19 hours or less is c. shorter tail to the left Because New York has a much larger population, it also has many more gas stations. b.
