Putting Values into Classes

Another way of reducing a large group of numbers to a more manageable size is to put similar values into classes or categories. For example, we might have the data on real estate parcel sizes. We could put each parcel into one of several categories: (1) greater than 10 acres, (2) 10 acres to 5 acres, (3) 5 acres to 1 acre, and less than 1 acre. In the Step-by-Step section of this chapter, you will do an exercise on classification of values.
