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
  • 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

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.
