NCERT Solutions for Class 8 Maths Chapter 5- Data Handling
Solving these NCERT Solutions are very important from the CBSE board examination point of view. Data Handling is the chapter that deals with the concepts that are mostly used in daily life. The chapter also includes 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 ‘grouped’ and presented systematically through ‘grouped frequency distribution’.
- Grouped data can be presented using a histogram. The 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 be presented using a 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 is collected in our day to day life is called Data. The graphical representation of the data clearly tells what he want to be represent. The different types of graphs are also used for representing the data dealing with pictograph, bar graph, double bar graph, pie charts, etc. this chapter generally covers organising data and grouping the data. The data is grouped using the frequency distribution table. In this chapter, the students also learn the concepts of probability.
Studying 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.
