Question

Definition of true class limits in statistics

Answer 1

Answer:

The boundaries that separate these intervals are called real limits. The real limit separating two adjacent scores is located exactly halfway between the scores. Each score has two real limits, one at the top of its interval called the upper real limit, and one at the bottom of its interval called the lower real limit.

Answer 2

Answer:

The lower class limit of a class is the smallest data value that can go into the class. The upper class limit of a class is the largest data value that can go into the class. Class limits have the same accuracy as the data values; the same number of decimal places as the data values. These class intervals are called Exclusive class intervals. True class limits are nothing but class boundaries. If we take exclusive class intervals from the above example, then lower boundary of class 10-20 is 0+10÷2=5 and upper boundary of class 10-20 is 20+20÷2=20.
