Let me apologize in advance for the brevity of today's post. You'll see very shortly that I've been a bit under the weather the last few days. It's the very fact that I've been on and off bedridden with fever that got me to thinking about temperature and thermometers.
Specifically, I've been wondering how accurate any readings of my temperature have been.
Over the course of an hour or so (I've been a bit bored), I took thirty measurements of my temperature to see just how much any one of those measurements got it right.
Let's cut to the chase, shall we?
To go back to last week, the mean and median are both 100.8, and the mode is 100.7. The standard deviation, or the average amount that any given measurement deviates from the mean, is around .6.
That means that the 95% confidence interval around my presumed actual temperature of somewhere around 100.8 is actually 99.6 to 102.0!
So, I guess my thermometer could be a bit more accurate. In fact, it's really quite poor.
