1. Proper Graphing for Scatter Plots, Line Graphs
Identify the independent and dependent variables from your data. What are you trying to show with your data?
Label the x-axis (independent variable). Label the y-axis (dependent variable)
Label the unit for the x and y axis.
Create a uniform scale for each axis. No breaks!
Origin on graph doesn’t have to be 0, 0. Axis can start at a specific number.
Include Legend if plotting more than one set of data.
Plot points clearly using up most of the graph
For Cellular Respiration Data: Independent variable = Time (minutes)
Dependent variable = Oxygen Consumption (ml)
y-axis scale may need to go from -.03 to 1.02
intervals .03
