I'm on autopilot right now at school, going through the motions. I figure if I go through the motions long enough, they'll be interesting again soon. Or eventually, one of the two.

Except today, as I'm going through the lessons in the book in the most old-fashioned of ways (lecture lecture lecture!) I hadn't read ahead because I'm basically working on a minute by minute basis right now. And then I get to the meat of today's statistics lessons.

We're teaching sampling methods and margin of error. By estimating the average age of women when they first give birth.


If you're interested, by the by, a 95% confidence interval puts the average age between 20.38 and 24.22 years of age. I'm not even an outlier.
