RD Sharma Solutions for Class 7 Maths Chapter 22:Data Handling 1 (Collection and Organisation of Data)

Data handling is the process of gathering, collecting, recording, and presenting information in a very useful way to others. For instance, representing complex information in charts and graphs is a type of data handling. In other terms, it is sometimes termed statistics. Data is widely used in science and maths.

In RD Sharma Solutions for Class 7 Maths Chapter 22 data handling 1, students study concepts based on data and related topics. For example, in statistics, the collection of data plays a vital role. So, the methods of collecting data are of two types. One is the primary data, and the other is the secondary data. Here, primary data is considered as assembling data that helps in receiving information for the first time. In contrast, secondary data is the one that others have already collected.

The main topic to cover is the organisation of collected data. Data organisation refers to the arrangement of figures so that the comparison of the mass amount of data may be facilitated and it can be used for further analysis. Next, frequency distribution is a common term that is described while talking about data and statistics. It can be simply defined as an overview of all the distinct values in a few variables and the number of times they occur.

Lastly, students also get to know about how frequency distribution is being constructed. This can be easily done in six steps.
1. Find the range of data 2. Decide the approximate number of classes 3. Determine the class interval sizes 4. Decide the starting point 5. Determine boundary 6. Distribute the data into respective classes.
