By comparing two way relative frequency table, we can comment if there is association between the two different categories. To understand, consider the following two-way relative frequency table given in example 2 on page 691:
$\begin{array}{|cccc|}\hline & \text{MP3 player}& \text{No MP3 player}& \text{Total}\\ \text{Cell phone}& 0.73& 0.27& 1\\ \text{Cell phone}& 0.59& 0.41& 1\\ \hline\end{array}$
As 0.73>0.59 one is more likely to have MP3 player when he has cell phone compared to when he has no cell phone. In other words, there is positive association in having call phone and MP3 player. By comparing two way relative frequency table , we can comment if there is association between the two different categories
