NCERT Solutions for Class 8 Maths Chapter 5 Data Handling

Data today has become a very important aspect of human life. The amount of data has also increased. Due to the vast amount of raw data, the step of handling and manipulation to obtain usable results has become very important. This process is known as data handling. This chapter deals with the basic knowledge of data handling. It starts from the basic processing of data, the arrangement of data to representation and interpretation of that raw data. The required processes are done to ensure an effective understanding of the data obtained. The data is represented in the form of charts and graphs, which makes the interpretation of the arranged data very easy. It gives the audience a pictorial form of the raw data where the usable results are very clearly visible. The chapter Data handling deals with the following intricacies:

Construction of a Quadrilateral

Construction of a quadrilateral is easy when the following are given:

• Looking For Information
  Data can be collected from various sources which may be trusted sources or non-trusted sources. Data extracted can be in large quantities and unorganised, which may seem like a random noise when tried to be interpreted.
• Organising Data
  The obtained raw data is unorganised, and thus it cannot be interpreted at that stage. The refining or processing of data begins with the organisation of the obtained data. In this process, the data is organised in a comprehensive way; for example, it can be arranged in ascending or descending order.
• Grouping Data
  At the next step, the obtained data is grouped into various sections for further study.
• Circle Graph Or Pie Chart
  The grouped data is represented in pictorial form or in the form of charts or graphs in this process.
• Chance And Probability
  This is the process in which tangible results are obtained from the data by employing various techniques.
