Reading Bar Graphs

A bar graph is a visual way to show information using bars of different heights or lengths to represent numbers.

To read a bar graph, look at the labels on the bottom and the numbers on the side to understand what each bar represents.

The height of a bar shows how many or how much of something there is.

The purpose of a bar graph is to compare different groups or categories of data.

To find the total, add the heights of all the bars together.

If one bar is taller, it means that category has more items than the shorter bar.

A bar graph uses bars to show data, while a line graph uses points connected by lines to show changes over time.

The most popular category is the one with the tallest bar.

If two bars are the same height, it means those categories have the same amount.

To find the difference, subtract the height of the shorter bar from the height of the taller bar.
