Book Free DemoSome of the graphs to be discussed in this section:
1. Bar graphs
2. Double bar graphs
3. Pie-graphs
4. Histograms
5. Line graphs
Bar graphs
Bar graphs make use of horizontal or vertical columns to represent data.
Example:
The points scored by \(4\) teams in a quiz competition is given below.
Double bar graphs
Double bar graphs are used to denote comparison between two entities.
Example:
The sales of bicycles made by \(4\) teams in March and April is represented below.
Pie-graphs
Pie-graphs or circle-graphs represent the whole of data in a circular form. This graph acquired its name from the famous food 'American pie'.
Example:
The percentage of time Amudha has spent on each subject during the study holidays is given below.
Histograms
Histograms are similar to bar graphs but are used to represent data for a continuous range of numbers.
Example:
The number of runs hit by the Indian cricket team during every \(10\) overs is given below.
Line graphs
Line graphs are otherwise called frequency polygons. Similar to histograms, it represents data for a continuous range of numbers. It is mainly used to describe data happening continuously over a period of time.
Example:
Let us use the same example discussed for histograms and represent it in a line graph.
Here, the period is the match duration.
