I am a math professor at the University of Puget Sound. My background is in operations research, and I teach typical OR courses such as optimization, modeling, and probability, as well as calculus, statistics, and differential equations.

My math blog, A Narrow Margin, includes (among other things) discussion of some of my favorite posts - of mine and of others - from math.SE.

comment Sample Standard Deviation vs. Population Standard Deviation
@Durin: No. If you actually know $\mu$ and you want to calculate $\sigma$ with all $N$ finite values from the population, then you're not estimating anything. In this case $\sigma$ should be calculated using the straight-up average of the squared-deviations - dividing by $n$ instead of using the estimation-bias corrected version that divides by $n-1$.
