Bar Graphs

A bar graph is a visual representation of data using bars of different heights or lengths to show the quantity of each category.

To read a bar graph, look at the height of each bar to see how much of each category is represented.

Each bar represents a different category or group in the data being displayed.

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

The highest value is found by identifying the tallest bar in the graph.

If two bars are the same height, it means that the two categories have the same quantity.

The title of a bar graph describes what the data is about.

You can tell which category is the most popular by looking for the tallest bar.

The x-axis is the horizontal line that usually shows the categories being compared.

The y-axis is the vertical line that usually shows the quantity or value of each category.
