12.2 Bar Chart

A bar graph can be defined as a chart or a graphical representation of data, quantities or numbers using bars or strips.

Bar graphs are used to compare and contrast numbers, frequencies or other measures of distinct categories of data.

Now, this bar graph below shows the different types and number of school supplies used by students. The more the height of the bar, the more is the number of the supply or item used.
