Erin and Chloe are trying to determine which number is not the mean, median, mode, or range of the data set 4, 3, 15, 11, 3, 8, 7, 5?

• 3

• 6

• 12

• 11

Calculate the range of the dataset: 3, 8, 12, 15, 20.

• 12

• 15

• 17

• 20

Answer explanation

To calculate the range, subtract the smallest value (3) from the largest value (20): 20 - 3 = 17. Therefore, the range of the dataset is 17.
