Question

The modal class of the following frequency table will be : 

• A. 10-20
• B. 40-50
• C. 0-10
• D. 30-40

Hint:

Unlike finding the median class, finding the modal class requires no extra calculation—you just need to spot the largest number in the frequency list!

Answer 1

The Correct Option is D

The problem is about finding the modal class of a given frequency distribution. The modal class is the class interval with the highest frequency.

From the frequency table provided:

Class interval	Frequency
0-10	2
10-20	4
20-30	5
30-40	8
40-50	1

Steps to find the modal class:

1. Observe the frequencies of each class interval.
2. Identify the class interval with the highest frequency.

From the table, the highest frequency is \(8\), which corresponds to the class interval 30-40.

Therefore, the modal class is 30-40.
