Hi,
I am using IBM-SPSS V24. I am experiencing a weird problem. When I copy any variable from 1 data set to another, the copying seems to work fine; but it reduces (and in some variables increases) the number of valid cases. For instance, in the original data set, I have 1028 valid cases. But when I copy it to a new data set the number of cases reduces to 978.
The data set is in this form, i.e., 1=Yes, and 2=0.
Any help in this regard would be highly appreciated.
Thank you.
