FAQs on RD Sharma Class 8 Solutions Chapter 27 - Introduction to Graphs (Ex 27.1) Exercise 27.1

1. How to use graphs effectively?

Graph is the best tool to illustrate complex relations between data in a simple form. Since the illustration is visual it makes it easy for the observer to understand the information. Graphs however are not needed to convey simple pieces of information which can be explained in one or two sentences. Preparing a graph requires some basic principles and proper use of caption, legends, axes and scales, symbols, headnotes, and also the figure number. The usage of these simple things makes a graph readable and legible. Correct graph type should always be chosen according to the data which needs to be presented. The vertical axis that is the y-axis should represent the dependent variable and the horizontal axis that is the x-axis should represent the independent variable for preparing a legible good graph. Graphs should always be plotted to scale. Following these principles can make the use of a graph effective.

Students can learn about the introduction of graphs and download the PDF format from Vedantu website.

2. What are the different types of graphs?

There are many types of graphs depending on the nature of the data present. They are

  • Line graphs used for the representation of continuous data

  • Bar graphs used for the representation of categories of data

  • Histograms are used to represent the frequency of numerical data organized in intervals when intervals between them are continuous. A special type of bar graph.

  • The Frequency Table represents several pieces of data present in between the intervals.

  • Line plots represent the frequency of data on a number line.

  • Circle Graph represents the relation between the parts of a whole. Hence they always add up to 1 or in percentage 100%.

  • Box and Whisker plot

  • Stem and leaf plot

However, the main three graphs are Line, pie, and bar graphs which include histograms also.

3. How do Graphs differ from Tables?

Graphs and tables both are easy tools for visualizing and breaking down information into illustrations. Both are handy and easy to understand. They differ in the following points

  •  Complicated data can be represented and analyzed more easily by graphs than tables.

  • The trends and comparisons of data are more easily understandable from Graphs than Tables.

  • Both are handy but tables are often preferred only for data having different units of measure.

4. What is the use of graphs in real life?

Graphs help to understand day-to-day calculations needed in real life. They are supportive of information that printing media starting from a daily newspaper to magazine all use graphs. Even e- media also make use of graphs. Graphs are significantly used in all areas starting from Finance, marketing, Insurance sales, and even in legal professions. Expenditure for the daily household can be best represented and calculated using circle graphs. They make calculations so easy and understandable that we have to rely upon the graphs on a daily basis.
