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.

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).

Bar graphs are useful for comparing information collected by counting.

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

What classroom size is the most common?

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

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.
