Next, they ask us, the data set contains, and they say how many variables and how many of those variables are categorical. So if we look up here, let's look at the variables. So this first column that is essentially giving us the type of drink, this wouldn't be a variable. This would be more of an identifier, but all of these other columns are representing variables. So for example, type is a variable. It can either be hot or cold. And because it can only take on one of, kind of a number of buckets, it's either going to be hot or cold, it's going to fit in one category or another.
