    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__

    "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     |
