In a recent survey, 8 people were each asked the number of times they have been on an airplane. Here is a list of the responses. \[ 8,10,21,8,9,13,24,12 \] Find the range of the data set.

The range of a data set is calculated by subtracting the smallest value from the largest value. In your responses, the smallest number is 8 and the largest number is 24. So, the range is calculated as: Range = Largest value - Smallest value = 24 - 8 = 16. Therefore, the range of the data set is 16. Speaking of common calculations, it's crucial to double-check your maximum and minimum values to ensure accuracy—those sneaky errors can easily skew your results! Plus, if you get a grasp of this concept early on, you'll save yourself headaches in more complex datasets later!
