NCERT Exemplar Class 8 Maths Chapter 2: Data Handling
The second chapter of NCERT Exemplar Solutions for Class 8 Maths, Data Handling, equips students with techniques to represent, interpret, and analyze data effectively. It begins with the basics of collecting and organizing data in the form of tables and tally marks. Students then learn to represent data using pictographs, bar graphs, and double bar graphs, which are essential tools for visual comparison. NCERT solutions for Class 8 Maths provide practice problems that guide learners step by step in drawing accurate graphical representations. A major focus of the chapter is on pie charts (circle graphs), which depict data as proportional parts of a whole. Students are taught how to calculate percentages and convert them into angles for correct representation. The chapter also introduces histograms and line graphs, helping learners understand trends over time. Through exemplar problems, students explore real-life applications such as comparing populations, sports data, and academic performance.
Another important concept covered is probability. Students learn the basics of chance, outcomes, and experimental probability through simple examples like tossing a coin, rolling a die, or drawing cards. These problems are designed to build logical reasoning and critical thinking. The NCERT Exemplar Solutions for Class 8 Maths for this chapter provide advanced questions that encourage analytical thinking. By solving them, students gain confidence in interpreting data beyond textbook examples. Moreover, NCERT solutions for Class 8 Science support this learning by promoting observation, analysis, and reasoning skills. Overall, this chapter not only strengthens mathematical skills but also makes students data-literate, an essential ability in today’s world of statistics and information technology.
