We have been given a data set that represents the math scores of five of Max's classmates. We are asked to find the range of the given data set.
Math score: 98, 76, 100, 88, 82.
Since we know range is the difference between the largest and smallest values of the data set.
We can see that largest score is 100 and smallest score is 76.
Therefore, the range of the given test scores is 24 and option B is the correct choice.
