How to calculate arithmetic mean of grouped data (Class Interval) | Step-by-Step for Beginners

In this video, we learn how to calculate the mean of grouped data using a simple step-by-step method.

When data is organized into class intervals, we cannot use the original values directly. Instead, we use the midpoint of each class interval and then calculate the mean using the grouped data formula.

This video is perfect for students of CBSE, ICSE, IGCSE (Cambridge) and beginners in statistics.

In this lesson, you will learn:

• What is the mean of grouped data
• Why we use class midpoints
• How to calculate class midpoints
• How to apply the grouped mean formula
• Solved examples

By the end of this video, you will be able to calculate the mean of grouped data confidently.
