## Information about the videoComparing Data in a Bar Graph

### Contents

A bar graph is like a picture that is made up of bars with different lengths. Each bar represents a different category. The length of each bar can tell us how often something happens or show us the number of items we have in each group.

We set up a bar graph like this. We have our data categories on one side and a number scale alongside the other. We put a label by the numbers to tell us what we are counting. To record the data, count how many times a category appears and draw a bar that reaches to the number.

Now that the data is in the shape of bars, we can see the information easily. We can answer questions like which weather had the most, or least amount of days. We can also use the bar graphs to help add or subtract the data.
