WebMethods of Describing Limits of Class Interval: Three methods of describing class limits are as follows: (a) Exclusive Method: In exclusive method of class formation, we add the interval 5 to the lower limit of the lowest class to find the upper limit of the class as 140 + 5 = 145. Thus our lowest class becomes 140 – 145.
