- Perhaps you should define what you mean by "the distribution of the
- darts." The distribution is obviously two-dimensional, but your other
- comments sound like you are dealing with a one-dimensional distribution.
- I don't know, for example, what "around the one s.d. area" means for
- your two-dimensional distribution.
-
- If you are looking at just the distance from the center as the
- statistic, then if the distribution of the dart locations were Gaussian,
- the probability distribution of the distance would definitely not be
- Gaussian (nor half-Gaussian).
