Explore the Data

• Open the Analyzing Two-Way Tables applet in a separate window.
• Enter the two-way table into the applet by either:
  • Copy and paste the table from the Lab Report word file, remember to not have any spaces within variable names, and press Use Table.
  • Open the data file donor.txt and paste two two columns (including headers) into the Paste Data window, and press Use Data.
Note, you can switch the roles of the explanatory and response variables.
• Check the Show table box to display the two-way table and the conditional proportions. Also verify the calculation of the MAD statistic from the Pre-lab.

(a) Write a one-sentence explanation of what the MAD measures and why it is useful here.
