## Making Sense of Information
Data is everywhere: in sports scores, weather charts, and your favorite video games. Understanding how to read and interpret graphs helps you make sense of the world.
### Types of Graphs
- **Bar graphs:** Compare amounts
- **Line graphs:** Show change over time
- **Pie charts:** Show parts of a whole
### How to Read a Graph
- Look at titles and labels
- Check the scale (what each unit represents)
- Compare heights, lengths, or angles
### Why It’s Useful
Reading data helps you spot patterns, make predictions, and answer important questions.
Examples
- Reading a line graph to see how your soccer team’s scores improve over a season.
- Using a pie chart to decide how to spend your weekly allowance.
