Data Handling is an important concept that assures the uprightness of the research data. We have information in the form of a numerical figure, no matter which field we take. Every value of this kind is known as an observation. Usually, the set of all the observation is called data. Different data management methods are used to handle termed as data, about which will be discussed in this chapter as well as in the higher classes. These solutions for Data handling are designed by subject experts as per the CBSE syllabus for the year 2019-20, prescribed by the board itself.

## NCERT Solutions for Class 8 Maths Chapter 5- Data Handling

Solving the NCERT Solutions for Class 8 is very important from the CBSE board examination point of view. Data Handling is one of the chapters in Class 8 maths that contain the concepts that are likely to be used in daily life. The chapter deals with different concepts related to Data Handling. Let us have a look at some of them.

- Data mostly available to us in an unorganised form is called raw data.
- In order to draw meaningful inferences from any data, we need to organise the data systematically.
- Frequency gives the number of times that a particular entry occurs.
- Raw data can be â€˜groupedâ€™ and presented systematically through â€˜grouped frequency distributionâ€™.
- Grouped data can be presented using histogram. Histogram is a type of bar diagram, where the class intervals are shown on the horizontal axis and the heights of the bars show the frequency of the class interval. Also, there is no gap between the bars as there is no gap between the class intervals.
- Data can also presented using circle graph or pie chart. A circle graph shows the relationship between a whole and its parts.
- There are certain experiments whose outcomes have an equal chance of occurring.
- A random experiment is one whose outcome cannot be predicted exactly in advance.
- Outcomes of an experiment are equally likely if each has the same chance of occurring. Probability of an event = Number of outcomes that make an event Total number of outcomes of the experiment , when the outcomes are equally likely.
- One or more outcomes of an experiment make an event.
- Chances and probability are related to real life.

## NCERT Solutions for Class 8 Maths Chapter 5- Data Handling

Information that we collect in our day to day life are called Data. The graphical representation of the data collected gives a clear idea of what it represents. The different types of graphs used to represent the data includes pictograph, bar graph, double bar graph, pie charts etc. The chapter 5 of Class 8 Maths, Data handling deals with organising data and grouping the data. The data can be grouped using frequency distribution table. In this chapter, the students also learn about the chances or probability of an event as well as how these probability can be represented.

Studying the chapter 5 of Class 8, Data Handling helps the students in:

- Reading bar-graphs,ungrouped data, arranging it into groups, representation of grouped data through bar-graphs, constructing and interpreting bar-graphs.
- Simple Pie charts with reasonable data numbers
- Consolidating and generalising the notion of chance in events like tossing coins, dice etc.Relating it to chance in life events.
- Visual representation of frequency outcomes of repeated throws of the same kind of coins or dice.
- Throwing a large number of identical dice/coins together and aggregating the result of the throws to get large number of individual events.
- Observing the aggregating numbers over a large number of repeated events.
- Comparing with the data for a coin.
- Observing strings of throws, notion of randomness
