This lab may have either 1 or 2 graphs.  There should be a minimum of 2 charts.  The first chart should be the data chart in which you calculated corrected differences (example shown.)  The second chart should be the data which corresponds to the data plotted on the graph.  If there are two graphs, then there should be 2 charts of data for the graphs.  I would use excel to get the equation of the lines so I could use the slope of the lines in my discussion.
