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

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

Bar Graphs

Bar graphs are useful for comparing information collected by counting.

8

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

9

What classroom size is the most common?

11

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!!!
