Answer 2

The size of the class interval 20-50​ is 30

Given:

The class interval 20-50​

To find:

The size of the class interval 20-50​

Solution:

Class size

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

• Class size will remains same for all class intervals
• Size of the class interval = Upper class limit - Lower class limit

Example:

• Suppose there is a class given by 1 - 10. 1 will be known as the lower   class limit and 10 is the upper limit.
• Then class size is given by 10 - 1 = 9.

Given class interval is  20 - 50

Here, 20 is lower class limit and 50 is upper class limit

Then class size = 50 - 20 = 30  

The size of the class interval 20-50​ is 30
