I have to admit that before entering the program, I thought of statistics as pure analysis, and I thought of data as the output of a mechanical process. This is actually the case a lot of the time. I mean, I did major in electrical engineering, so it’s not all that surprising I saw data in that light.

Don’t get me wrong. That’s not necessarily a bad thing, but what I’ve learned over the years is that data, while objective, often has a human dimension to it.

For example, look at unemployment again. It’s easy to spout state averages, but as you’ve seen, it can vary a lot within the state. It can vary a lot by neighborhood. Probably someone ...
