Class width is the difference between the Upper class limit and the Lower class limit of a class interval.
Class Width = Upper Class Limit − Lower Class Limit.
For example: For a class interval, 163−175,
Class Width =175−163=12
The class width is 5, the lower-class limit is 10, what is the upper-class limit of the same class?
What is the width of the class interval 50-90?
In a frequency distribution table with 12 classes,the class-width is 2.5 and the lowest class boundary is 8.1,then what is the upper class boundary of the highest class?
