Answer 11

Steps to make a frequency table:
1. Put scores in ascending order. If data set is voluminous, a stem and leaf plot might help.
2. make heading of a table of "distinct" scores in column 1, frequency in column 2.
3. start from the lowest values, enter a new score in column 1, enter the number of times it appeared in column 2.
4. repeat 3 until all data exhausted.
