Understanding Charts and Graphs

Interpreting data means reading tables, graphs, and charts to find answers. This is a key skill for both the HSPT and real-life situations.

Types of Data Displays

  • Bar Graphs: Compare different groups.
  • Line Graphs: Show changes over time.
  • Pie Charts: Show parts of a whole.

Key Skills

  • Identify trends (Is something increasing or decreasing?)
  • Compare values (Which bar is taller?)
  • Calculate totals (What’s the sum of all pieces?)

Everyday Life

You use data interpretation when reading sports stats, the weather forecast, or social media trends!

Examples

  • A bar graph shows 10 students like pizza, 8 like burgers, and 6 like salad. Which food is the most popular? (Pizza)

  • A pie chart shows 1/4 of students chose blue, 1/2 chose red, and the rest chose green. What fraction chose green? (1/4)
