The steps to constructing a frequency table are as follows. First, put the numbers in order. The scores in the question would first be listed as: 1,2,4,5,6,7,7,8. Second, add up how often each score occurs. Each of the scores occurs once, except for the 7. Third, list each distinct score in a table along with the frequency it occurs (and optionally the percentage that the score occurs out of all the scores. Thus we would get the score of 2 as the second line of the frequency table, occurring once, representing 12.5% of all scores. The answer is A.
