These solutions are available at Vedantu’s official site (vedantu.com) and can be downloaded free of cost.

6. What are the types of data handling according to Chapter 4 of Class 8 Maths?

Data handling is the process of collection and representation of data in a manner, which is convenient to interpret by others. To effectively present the collected data in east interpretable form there are many methods;

Pictograph

Line Graph

Bar Graph

Cumulative Tables and Graphs

Histograms

Stem and Leaf Plot

Distribution of frequency

Dot plots

The most common and widely used method of data handling is the bar graph method as it is the most straightforward, easily interpretable and convenient method.

7. What is data handling as discussed in Chapter 4 of Class 8 Maths?

The process of collecting, storing and representing data in a manner that is very straightforward, convenient to interpret and easy to draw inference from is known as data handling. It helps that a large amount of information gathered from any project can be presented in a manner so that other people can understand with ease in less time. For example, a circular chart of types of species of insects according to their population, a bar graph of a student's marks scored, etc.

8. How data handling will help students in day to day life according to Chapter 4 of Class 8 Maths?

Any circumstance or problem that we need to investigate necessitates the gathering of data, which must then be displayed in such a way that it gives a clear grasp of the problem's details while also analysing whether solutions are possible. The data can be depicted pictorially through a range of various kinds of graphs, such as a pictograph, bar graph, and double bar graph, according to the NCERT solutions for Chapter 4 of Class 8 Maths. When we collect data, it's frequently unstructured or unorganised and makes little sense. To create usable inferences, we need to organise the data in a methodical way. NCERT's solutions Chapter 4 of Class 8 Math begins with an explanation of the concept "frequency," which refers to the number of times a data item appears. A frequency distribution table will be taught to the students.

9. What are the important topics covered and how many questions are there in Chapter 4 Class 8 Maths?

With the use of pertinent frequency distribution tables, bar graphs, double bar graphs, histograms, and pie charts, NCERT Solutions Chapter 4 of Class 8 Maths delves deep into the notion of data processing. In addition, the idea of probability was covered in the chapter's final part. There are 16 problems in NCERT Solutions Class 8 Maths Chapter 4 Data Handling, 10 of which are short-form and 6 of which are long-form.
