# RD Sharma Solutions for Class 8 Maths Chapter 23:Data Handling -I (Classification and Tabulation of Data)

The chapter covers the basic ideas of data handling, collection of data and interpretation of data. The concepts of data handling in this chapter revolve around understanding what is data. Any mathematical value or number collected from any source is known as raw data. The raw data is taken and analysed to provide results depending upon the questions posed. The chapter also teaches the students about the concepts of representation of data.

When data is represented in a table, it is known as the tabular representation of data. The data presented along with its frequency is known as the frequency distribution. A frequency distribution can be grouped or ungrouped. Grouped representation is when the data is grouped in bunches and is represented along with its frequency. Ungrouped data includes the representation of individual data.

The chapter elaborates on the various topics in the following stages:

• Understanding the meaning of the data that has been provided.
• Responding to inquiries with the information provided.
• Making frequency distribution based on the concepts taught.
• Determining the difference between the continuous and non-continuous groups.

The Maths Chapter 23 Data Handling -I (Classification and Tabulation of Data) deals with the frequency distribution table, organisation of data.
