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

Step 1: Understanding the Concept:
In a grouped frequency distribution, the modal class is the class interval with the highest frequency. It represents the most common range of values.
Step 2: Comparing Frequencies:
Looking at the frequency row:
Frequency of 0-10 = 2
Frequency of 10-20 = 4
Frequency of 20-30 = 5
Frequency of 30-40 = 8 (Highest)
Frequency of 40-50 = 1
Step 3: Identification:
The maximum frequency is 8, which belongs to the class 30-40.
Step 4: Final Answer:
The modal class is 30-40.
