Use the given data to construct a frequency distribution On

Use the given data to construct a frequency distribution. On a math test, the scores of 24 students were 99 78 79 67 79 79 99 89 79 68 88 78 78 88 79 78 88 79 78 89 78 88 89 67

Solution

Step1: Put the data into logical groups

Step2: Count the number of data points in each group.


You are told to use 4 groups, with the first one having a lower limit of 60.

Sensible group choices would be:
Group1: Score 60-69
Group2: Score 70-79
Group3: Score 80-89
Group4: Score 90-99

For each group, the frequency is just the number of scores that were in that group.
