In the Data Analysis Tutorial we learned how to report the results of an experiment, but we did not bother with the details of getting the data values. For example, to determine the acceleration due to gravity, we would have to make some more feasible measurements; such as the position and time of a falling body.
In this section, we will deal with the more complicated problem of analyzing two sets of data points that are related in some way. We will graph the data sets to look at the relationship, try out a theoretical model, and then summarize our results (as before).
