The range of a set of scores is calculated by taking the difference between the highest and the lowest scores in the set. For the scores provided: 5, 7, 9, and 15, the highest score is 15 and the lowest score is 5.
To find the range, we perform the following calculation:
Range = Highest Score – Lowest Score
Substituting the values:
Range = 15 – 5 = 10
Therefore, the range of the set of scores 5, 7, 9, and 15 is 10.
