Answer:
Step-by-step explanation:
Class limits are the minimum data value(lower) and maximum data value (upper) that a class can contain. They usually have the same numerical accuracy as the original data values.
Class boundaries are boundary lines that mark or separate where one class stops and the other begins. The lower class boundary of a given class is got by finding the average of the previous upper class limit and the given lower class limit while the upper class boundary is got by finding the average of the given upper class limit and the next lower class limit.
