Suppose 50 people are randomly chosen
And asked "Do you fancy this yogurt that's frozen?"
50 is viewed as the size of our sample;
It’s not to be viewed as a variable’s value.
What's one guy's answer? Well, that's not rhetorical;
It is a variable that's categorical.
The way you can view it, the way you can know:
Each person we surveyed says 'yes' or a 'no'.
Of course, you could tally each label's amounts
For a summ'ry statistic from each of the counts.
But that doesn't mean that a variable’s numerical;
Each value's a category whose tallies are clerical.
We know that a variable is very able
To yield useful data all in a nice table,
But we must assert categorically
Variable type is important, you see,
To know just what summ'ries and tools you can use
So bar graphs and histograms won't be confused!
