Work Step by Step

Normally, this would be a table. The first number in the answer is the score. The second number (separated from the score by a dash) is the frequency of the score. A frequency distribution lists each category of data (in this case scores), and the frequency of each score (or the number of times each score occurs. Since the score 3 occurs just one time, its frequency is 1. The score of 4 also occurs just one time, so its frequency is also 1. The scores of 5 and 6 occur three times each, so each of their frequencies is 3. The score 7 has a frequency of 2. The score of 8 has a frequency of 2 (it occurs twice in the list). The score of 9 occurs two times, so its frequency is 2. And the score of 10 only occurs once, so its frequency is 1.
