STAT 200 - Chapter 9 - Two-Way Tables We will introduce chapter 9 here, and come back to it again towards the end of the course, once we have discussed inference. In these notes, we will talk about summarizing the relationship between 2 categorical/qualitative variables. In the next chapter (chapter 2), we will talk about examining the relationship between 2 continuous/quantitative variables. To examine the relationship between 2 categorical variables, we start by making a two-way table (sometimes called a contingency table). A two-way table is useful for describing the relationship between two categorical variables. A two-way table shows the marginal distribution for each variable, as well as the joint distribution of the 2 variables at the same time and also the conditional distribution of one variable, conditioned on a category of the other variable. Exercise : How is smoking related to alcohol use? (have data for 65 individuals or cases ).

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
