Assessing One-Way Frequencies

Introduction to the One-Way Case

Let us start with the simplest example: examining the distribution of observations in a single categorical variable, like the Size variable in the textbook example. We refer to counts derived from a single categorical variable as “one-way” frequencies. There are two major possibilities here, namely:

• Assessing the distribution of one-way frequencies
• Assessing one specific category

The following sections expand on these options.

Assessing Distribution of One-Way Frequencies

The distribution of a single categorical variable can generally only be assessed against some benchmark distribution. In the previous section, I gave two examples, namely:

• Testing your ...
