Question: In a frequency distribution, if the class intervals are 0-10, 10-20, 20-30 and their frequencies are 5, 10, 15, what is the mode?

Options:

Correct Answer: 20

Solution:

Mode is the class with the highest frequency, which is 20-30.

In a frequency distribution, if the class intervals are 0-10, 10-20, 20-30 and their frequencies are 5, 10, 15, what is the mode?

Correct Answer: 20-30

Step 1: Identify the class intervals given in the frequency distribution. They are 0-10, 10-20, and 20-30.
Step 2: Identify the frequencies corresponding to each class interval. They are 5 for 0-10, 10 for 10-20, and 15 for 20-30.
Step 3: Compare the frequencies to find the highest one. The frequencies are 5, 10, and 15.
Step 4: Determine which frequency is the highest. The highest frequency is 15, which corresponds to the class interval 20-30.
Step 5: Conclude that the mode is the class interval with the highest frequency, which is 20-30.

Frequency Distribution – A representation of the number of occurrences of each value or range of values in a dataset.
Mode – The value or class interval that appears most frequently in a dataset.
Class Intervals – Ranges of values that group data points for analysis in a frequency distribution.
