# Math Help - Construct a frequency distributution

1. ## Construct a frequency distributution

Hi can someone help me with this? The question is 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

Construct a frequency distribution. Use 4 classes beginning with a lower class limit of 60. Score_____Frequency__

2. "construct a frequency distribution" just means do the following:

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.

Code:
Score     |  Frequency
---------------------
60-69     |       3
70-79     |
80-89     |
90-99     |
