**Independent vs. Dependent Variable**Dependent Variable Independent Variable**Independent vs. Dependent Variable**If you have categories use a bar graph Dependent Variable Independent Variable**Color of Paper vs. Score on a Test**If you have categories use a bar graph Score on a Test Blue Green Yellow Color of Paper**Color of Paper vs. Score on a Test**Graph the average (mean) Include a range (high and low) Score on a Test Blue Green Yellow Color of Paper**Independent vs. Dependent Variable**If you have quantities use a best-fit line graph Dependent Variable Independent Variable**Ramp Height vs. Time**If you have quantities use a best-fit line graph Evenly space the numbers Time to roll down the ramp (s) Always start with zero! 5 10 15 20 25 Height of a ramp (cm)**Ramp Height vs. Time**If you have quantities use a best-fit line graph Time to roll down the ramp (s) 5 10 15 20 25 Height of a ramp (cm)**Ramp Height vs. Time**Put dots for each data point Time to roll down the ramp (s) 5 10 15 20 25 Height of a ramp (cm)**Ramp Height vs. Time**Draw a line that best fits your data Time to roll down the ramp (s) 5 10 15 20 25 Height of a ramp (cm)**Independent vs. Dependent Variable**Dependent Variable Independent Variable
