Question

The width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10. What is the upper class limit of the highest class?

Answer 1

Given:-

• The width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10.

⠀

To find:-

• Upper class limit of the highest class.

⠀

Solution:-

We know that,

• lower limit of the lowest class = 10

⠀

Here,

• Width of each class = 5
• Total number of classes = 5

⠀

According to the question,

⛦ After finding the upper class limit of the lowest class, the five continuous classes in a frequency distribution with width 5.

⠀

⇛ First class = 10 - 15

⇛ Second class = 15 - 20

⇛ Third class = 20 - 25

⇛ Fourth class = 25 - 30

⇛ Fifth class = 30 - 35

⠀

Hence,

• the upper class limit of the highest class is 35.
