Reading a Bar Graph
A bar graph is a picture that helps you compare numbers. Imagine that a class votes for favorite fruits. Eight kids pick apples, five pick bananas, three pick grapes, and six pick oranges. You could write the numbers in a list, but a bar graph makes the results easier to see.
Every bar graph has a title that tells what it is about. Ours might be called Favorite Fruits. A bar graph also has labels along the bottom that tell what each bar means, such as apples, bananas, grapes, and oranges. Along the side is a number line, called a scale, that shows how many votes each bar stands for.
Each fruit gets a bar. The taller the bar, the more votes the fruit got. The apple bar is the tallest because it has eight votes. The grape bar is the shortest because it has only three.
To read a graph, look at the top of a bar and slide your eyes over to the scale. You can quickly see which fruit won and by how many votes. Apples beat bananas by three.
