Are birthdays quantitative or qualitative?
My teacher had a set of data on the board about baseball players, and it involved their birthday as 1/23/45 or something similar. He asked us if the data was quantitative or qualitative and then he got stumped and moved on, leaving us confused.

The difference depends not only on what data set you look at, but how you look at it. Sometimes the same data can be examined either way. A simple test would be see if it matters, to your analysis, if you re-order the data.
The average age of a MLB player today is about 28.6 years. That's a quantitative measure that indicates a distribution of birthdays that centers somewhere near the summer of 1988. If you are interested in age, you can't put those born after 1995 "before" - that is "older than" - those born before 1985 without affecting this measure. So its a quantitative analysis.
If you are interested in which month produces the most players, its a qualitative analysis. It doesn't matter if you count those born in November before those born in May. In fact, some of them were.
