Which has the smallest standard deviation?

anonymous · Answer

The sample with the smallest s.d or standard deviation will mean it is less dispersed  from its mean.

If you have a problem with finding the s.d, we can discuss it by first identifying what kind of statistical problem you have for there are different formulas for different situations.
