• In a bar graph, each bar or column is the same width.

• The base of all bars will be the same.

• The data value is represented by the height of the bar.

• Each bar has the same distance between them.

7. What are the types of Bar Graphs?

Bar Graphs help us structure Data to help us understand it better. It is a simple visual that can easily be made once all the information is collected. To help understand different types of information better there are different types of Bar Graphs like -

• Vertical Bar Graphs - This Data is represented vertically.

• Horizontal Bar Graphs - These Graphs are represented horizontally

• Stacked Bar Graph - Also known as the clustered Bar Graph is used to display information of two different variables and sources.

• Grouped Bar - This is also known as a clustered Bar, though it is very different from a stacked Bar. This is used to show Data in two or more categorical Data.

8. How are Bar Graphs different from Histograms?

The primary distinction between Histograms and Bar Graphs is that the Bars in a Bar Graph are not next to each other, but the Bars in histograms are. A Bar Graph is a Graphical representation of exact Data made up of rectangular Bars with equal gaps between them, whereas a histogram can be termed as a Graphical representation of Data made up of rectangular Bars with no gaps.

Histograms are used to represent distributions of variables and plot quantitative Data such as Data of population changes every year, marks obtained, and monthly salary, whereas Bar Graphs are used to compare various variables and are used to plot categorical Data such as Data of types of animals, types of colours, types of movies, and so on.
