15531182. ramankaurdeep9080 ramankaurdeep9080 04/05/2020 Mathematics Middle School answered For qualitative data, the relative frequency for a class is computed as A) Class width divided by class interval. What would be the relative frequency of the seven (7) data points? It turns out that 50 of these supermarkets charge a price between $8.00 and $8.99 for a pound of coffee. Answered: You have a class with a frequency of | bartleby A. class width divided by class interval. b. box plot C. frequency divided by the class interval. 27 D. frequency divided by the total frequency . Then create a tally to show the frequency (or relative frequency) of the data into each interval. December 13, 2009. a. Relative Frequency | Formula and Examples - BYJU'S How to find frequency in statistics class 9 - The relative frequency can be calculated using the formula fi=fn f i = f n , where f is the absolute frequency. For example, the following table shows the frequency distribution of gas prices at 20 different stations.\n

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. a. 5% a. wrong crosstabulation c. relative frequency Similarly, the relative frequency of prices between $3.75 and $3.99 equals 4/20 = 0.20 = 20 percent.

One of the advantages of using a relative frequency distribution is that you can compare data sets that don't necessarily contain an equal number of observations. With a sample size of 20 gas stations, the relative frequency of each class equals the actual number of gas stations divided by 20. a. 20 Refer to Exhibit 2-4.
