Calculating Z Scores for Individual Points and adding to the attribute table

I am carring out a spatial anaysis of archeological finds to see whether they are clustered or not. Initially I have carried out a NN and Ripleys K to determine whether or not the points are clustered (most are).

I would like to extend the analysis to see if these clusters are statistically significant or not.

Therefore is it possible to generate a Z score for each of the points that can be added as a column in the attribute table? The idea being that this score can then be used as the input field in the Morans I test for significance.

Thanks in advance for any help you may be able to give me with this! :-)
