Suppоse yоu hаve the fоllowing test scores for а clаss of 30 students: 84, 92, 78, 88, 65, 72, 93, 88, 75, 82, 79, 90, 87, 68, 76, 84, 78, 85, 91, 77, 89, 83, 70, 81, 74, 86, 72, 94, 76, 80 To create a grouped frequency distribution, you first need to decide on the width (size) of the intervals or classes (also referred to as groups). Let's say you decide to use intervals of 10 points each, starting from 60 to 100. Here's the grouped frequency distribution table: Test Score Intervals Frequency 60-69 3 70-79 9 80-89 13 90-99 5 Total 30 Given the information above, which of the following statements is an example of how a relative frequency distribution calculated?
