  2. 2 What is a graph? • A graph is a visual display of information or data. • Why use a graph? • It allows us to interpret information faster and easier than a data table.

  3. 3 Line Graphs • Line graphs are effective at showing a relationship where the dependent variable (DV) changes due to a change in the independent variable (IV). • The DV is placed on the y-Axis (vertical axis). The IV is placed on the x-Axis (horizontal axis).

  7. 7 Bar Graphs Bar graphs are useful for comparing information collected by counting.

  8. 8 Again, tables aren’t always the most efficient way to interpret data.

  9. 9 What classroom size is the most common?

  11. 11 Circle Graphs • Circle graphs are sometimes called pie graphs. • Circle graphs show how a fixed quantity is broken down into percentages.

  13. 14 Important Stuff • Remember: The independent variable (IV) goes on the X-axis (horizontal axis). • The dependent variable (DV) goes on the Y-axis (vertical axis). • Label both axes!!! • Include your units!!! • Keep your scale consistent for each axis.
