Bear in mind that the proper weight treatment really depends on the nature of the weights and the procedure to be used.  Standard SPSS weights are frequency weights and can expand the number of cases correspondingly.  However, if you have survey weights from complex sampling designs, the procedures in the Complex Samples option are designed to take these fully into account.

Hello,

I think that I might be doing some analyses incorrectly; I've been using weights, which have averaged over 1  
(they are based on volumes/response counts).  In SPSS, are these interpreted as frequencies?  If so, I believe that I've been falsely inflating the significances.  Should I normalize the weights (divide by the mean, so that the new average is 1)?

Thank you very much,

Barry
