Given the set of data points {7, 9, 12, 15, 16, 20, 22}. What is the mid-range of the data set?
Step 3: Calculate the mid-range. \((7 + 22) / 2 = 14.5\)
Step 1 :Step 1: Identify the smallest and largest numbers in the data set. In this case, the smallest number is 7 and the largest number is 22.
Step 2 :Step 2: Use the mid-range formula, which is \((\text{smallest number} + \text{largest number}) / 2\). Substituting the values from our data set, we get \((7 + 22) / 2\).
Step 3 :Step 3: Calculate the mid-range. \((7 + 22) / 2 = 14.5\)
