- Can someone explain why calculating the Standard Deviation (SD),
- for small samples, with (n-1) in the denominator is better than
- doing so with (n) in the denominator? I'm sure that there's
- a perfectly good reason for doing so. But we, lowly engineers
- aren't usually told the reason. Thanks now, for your response later.;-)
