Why each option
The range value in a dataset is calculated by subtracting the minimum value from the maximum value. This statistical measure provides an indication of the spread or dispersion of the data.
9 would be the range if the difference between the maximum and minimum values was 9, which is not indicated by the correct answer.
10 would be the range if the difference between the maximum and minimum values was 10, which is not indicated by the correct answer.
12 would be the range if the difference between the maximum and minimum values was 12, which is not indicated by the correct answer.
The range of a data set is determined by finding the difference between the highest (maximum) value and the lowest (minimum) value present in the data set. For the given dataset (which, for the answer 13, must have a maximum value that is 13 units greater than its minimum value), 13 represents this calculated difference.
