sure – you can do it in Excel, if you’re so inclined….IF you assume you’re comparing it to a normal distribution (and use a z-test).

 

Luc Anselin has written gobs on this – the possible pitfalls of comparing an observed spatial distribution to a hypothesized random distribution.  Maybe this makes more sense in the physical sciences, but it may be problematic for a lot of concerns.

 

Why not just download the free package GeoDa, which will do a randomization-based significance test for you, and you can set it to do as many permutations as you like (it’s incredibly fast, takes just a few seconds, even for an extremely large dataset).
