Problem
Given a data set {3, 7, 6, 10, 13, 15, 20, 22}, calculate the mid-range.
Solution
Step 1 ：Step 1: Identify the smallest and largest numbers in the data set. In this case, the smallest number is 3 and the largest number is 22.
Step 2 ：Step 2: Add the smallest and largest numbers. So, \( 3 + 22 = 25 \)
Step 3 ：Step 3: Divide the sum by 2 to get the mid-range. So, \( \frac{25}{2} = 12.5 \)
