CliffsAP Statistics - Page 26 Classes are contiguous - you can't miss out a class because it's empty, for example. A histogram lists the classes along the x-axis of a graph and uses bars to represent the frequency of each class along the y-axis. Our smallest data value is 1.1, so we start the first class at a point less than this. So the class width — notice that for each of these bins (which are each of the bars that you see here), you have lower class limits listed here at the bottom of your graph. Encyclopedia of Research Design - Volume 1 The height of a bar indicates the number of data points that lie within a particular range of values. In this case, 9 4 = 2.25 9 4 = 2.25.
