# NCERT Solutions for Class 8 Maths Chapter 5 Data Handling

NCERT Solutions for Class 8 Maths Chapter 5 Data Handling - This chapter is introduced here to develop the skills of interpreting data from various kinds of graphs. The main objective of introducing this topic into the curriculum of mathematics in class 8th is that after solving all problems students would be able to understand any kind of data presented in any kind of data represented graph can be understood easily. Many students face problems in this topic because it is a new concept for them. To help students the NCERT Solutions for Class 8 Maths Chapter 5 Data Handling are solved by the maths experts.

Our life is surrounded by numbers, for example, runs made by a batsman, marks scored by students, height, weight, etc. all these are data. Basically, data is the collection of information and observations. In NCERT Class 8 Maths Chapter 5 Data Handling we are going to learn how to manage data in a systematic manner and how to organize this data in the form of charts and graphs. Data handling is a good way to keep record and organize the data in a systematic manner. Data can be represented in various forms or there are various types of the graph to represent the data. General types of graphs used to represent data the data are as follows:

1. Tabular Chart- The most simple form of data presentation is Tabular chart where data is always represented in matrix form which is most easy to the readable form of data representation.

2. Pie Chart - Pie Chart is the chart where the data represented either in percentage or in the angle made in the middle by that particular sector of the circle.

3. Bar Graph - It is the most preferred method of data representation where data always present in bars and multiple bars makes a bar graph.

4. Line Graph - Line Graph is the extended and updated version of Bar Graph where the top of every bar is connected to the next bar’s top and adjoining of these tops makes a line graph.

 Formula $\dpi{100} Probability = \frac{The \:number \:of \:outcomes\: that \:make \:an\: event }{Divided\: by\: total\: number\: of\: outcomes\: of\: the\: experiment}$ Probability of an event is the number of outcomes that make an event divided by total number of outcomes of the experiment. When the outcomes are equally likely

To develop the grip on the topic, after every concept  NCERT provides solved examples, daily life activities and exercises for the students. In this chapter, there are 3 exercises with 16 questions.
