Reading and Interpreting Graphs

Mastering Data Visuals

Graphs and charts turn numbers into pictures, making complex data easier to understand.

Tips for Success

  • Always check the title and labels to know what the graph shows.
  • Look at the scale—are the numbers spaced evenly?
  • Notice trends, highs, lows, and anything unusual.

Why This Matters

Understanding graphs helps you quickly spot patterns, compare groups, and avoid misinterpretation.

Examples

  • Spotting which month had the highest sales on a bar chart.

  • Comparing different groups in a pie chart.
