| Nov 6, 2020 at 23:10 | comment | added | Gerry Myerson | George, are you using the sample variance formula where you divide by $n$, or the one where you divide by $n-1$? | |

| Nov 6, 2020 at 18:29 | comment | added | Michael Lugo | I've run into this problem in trying to come up with exercises in statistics classes where the arithmetic will work out nicely. If you're interested in small lists of short integers, one way is to just pick random lists and compute their standard deviations. | |
