A data set contains the ages of students in a class. The ages range from 12 to 18. If the data is divided into 6 classes, what is the class width?

Step 1 ：Step 1: Find the range of the data by subtracting the smallest value from the largest. \(Range = Largest Value - Smallest Value = 18 - 12 = 6\)

Step 2 ：Step 2: Divide the range by the number of classes. \(Class Width = \frac{Range}{Number of classes} = \frac{6}{6} = 1\)
