Thank you for offering the random number generator. I have used it for a research on the effects of target specific communications in a N=2000 population of Dutch War Veterans. In the experimental setting it was necessary to randomise the research population and to divide them over four sub-groups, similar in size. The only acceptable way was to do so by adding a randomised variable in SPSS. Afterwards it was possible to assign the subjects to one of the groups by sorting on the randomized variable. Of course I gave due credit in the report by mentioning your service and revealing the URL.
