Just a note

Notice that, because we are suggesting pig age is an explanatory variable, by convention it is plotted along the x-axis. Whereas, on a contingency table, by convention the explanatory variable runs vertically. However, just because a variable is plotted on the x-axis, or used to label rows, does not imply it is an explanatory variable.
