Question

Name: Instructor: Date: Section: 6. Construct a relative frequency distribution for this data. In each class, the relative frequency corresponds to the percent of the total data that falls in that class. This percent is expressed in decimal form rounded to three places. Relative frequemcy- cotal uaerot class frequency uency =--. In this data set we have 53 data values. So, in each calculation our denominator is 53. Number of College Credits Completed 9-31 32-54 55-77 78-100 101-123 Frequency Relative Frequency 15 15 13 IS/53 ~ 0.283-28.3% 15/53-0.283-28.3% 1353-0.245-24.5% 4/53-0.075-7.5% 653-0. 1 1 3-11 .3% Notice that the sum of the fractional parts is exactly 1 while the sum of the percentages is 99.9%. The missing 0.1 % is due to our round-off error. It is wise to check for careless errors by checking that the sum of relative frequencies is equal to 1.

Explanation / Answer

Following table shows the relative frequency distribtuion:

Number of college Credits Completed Frequency , f Relative frequency ,f/53 Percentage 9-31 15 0.283 28.3 32-54 15 0.283 28.3 55-77 13 0.245 24.5 78-100 4 0.075 7.5 101-123 6 0.113 11.3 Total 53 0.999 99.9
