Bar Graphs
allow you to
notice and interpret
data easily.

They make comparisons between different numbers very easy to see.

They clearly show trends in data, meaning that they show how one variable (number) is affected as the other rises or falls.

Figuring out what the numbers mean on a bar graph can be fun !
