All classes should have the same class width. In this case, class width equals to the difference between the lower limits of the first two classes. The class midpoint (or class mark) is a specific point in the center of the bins (categories) in a frequency distribution table; Its also the center of a bar in a histogram. It is defined as the average of the upper and lower class limits. Definition: Class Boundary. Class boundary is the midpoint of the upper class limit of one class and the lower class limit of the subsequent class. Each class thus has an upper and a lower class boundary. It must be noted that upper class boundary of one class and the lower class boundary of the subsequent class are the same. Class boundaries are not a part of the dataset.
