​

Answer 1

Answer: Hello & Namasthe

In a class interval,we make Limits such that grouping of values should be particular and noticeable. So in a Class limits LHS is Lower limit & RHS is Upper limit.

So in ur given class interval 10-20

10-lower limit

20-upper limit

Note : Clearly, the upper limit of a class interval is the same as the lower limit of the next class interval in case of overlapping groups. Next, let the class intervals for some grouped data be 1 – 5, 6 – 10, 11 – 15, etc...

Class size: Difference between the true upper limit and true lower limit of a class interval is called the class size.
