NCERT Solutions for Class 8 Maths Chapter 15 Introduction to Graphs

iacst-2022

In the chapter named Introduction to Graphs, students learn to represent various sorts of information with different sorts of graphs. The various sorts of graphs are as follows: bar graphs, pie graphs, line graphs and linear graphs. This chapter will help the students in learning how to locate a point and coordinate in a chart. A sum of 3 exercises is available in the chapter to help the students understand the concepts of Graphs.

Introduction to Graphs
Graphs are a visual representation of data collected. Its purpose is to show numerical data in physical form to be understood quickly, easily and clearly.

Bar Graph
A bar graph is commonly used to show a comparison of two or more different categories. Parallel vertical bars are used to represent the data on a bar graph.

Pie Charts
A pie-graph or pie chart is used to represent the parts of a whole. A circle is used to represent the whole

Histogram
A histogram is just a bar graph, which is used to group numbers into ranges. It shows data in intervals.

Linear Graph
It is a graph where all the data points can be plotted on a single straight line

Application of Graphs
Conditional on how the values of a variable change for another, we have two independent and dependent variables.

  • Independent (or control) Variable is the one, where its value doesn't change for another quantity.
  • Dependent Variable is the one, where the value does change for another quantity.

 

Line Graph
A line graph is used to plot data that changes over a certain period of time.

Cartesian Plane and Coordinate Axes
Coordinate axes are formed and defined by two perpendicular number lines: the x−axis, which is horizontal and the y−axis, which is vertical.
