The harder way: without the template. We begin by sorting the data in descending order and creating its cumulative relative frequency distribution. (The cumulative relative frequency is just a running total of the relative frequency column. Here, for example, 0.0509 = 0.2990 + 0.2100, then 0.6541 = 0.2990 + 0.2100 + 0.1450, and so on.)

We can calculate the relative frequency for each class as follows: Ex: Class Frequency ( f ) Cumulative. Frequency Relative. Frequency (f / n) 90-99 4 4 .20 80-89 6 10 .30 70-79 4 14 .20 60-69 3 17 .15 50-59 2 19 .10 40-49 1 20 .05 Note: The sum of the relative frequencies should be 1(or 100%.) Class Exercise: Add a relative frequency column to ...
