I have almost all of my data (except for some retest data that is still trickling in) and I'd like to start cleaning some of it. I found the link to Ron Dotsch's instructions on managing the data for use with SPSS, and I intend to follow them. However, I have discovered that Inquisit has apparently assigned every one of my participants the same subject number. I guess I'm going to have to use date and time data to manufacture a new distinguishing id for each participant. Is there any easy way to do this in Inquisit or SPSS? Any ideas?
