Answer 1

Not sure this is what you are seeking, but this is what I got from the Internet:

Class Boundary : Class Boundary is the number used to separate the two different classes. It is the midpoint between the upper class limit of a class and the lower class limit of the next class. Each class have both upper and lower limit boundary.
