Hi. I have a dataset with about 3,000 records. I need to assign a unique ID to these records but I don't want it to just be 1, 2, 3 or A, B, C. I need it to be something that won't be able to be de-coded. Is there a way to create a list of random numbers or alpha-numerics that I could then add as a variable to my dataset? My dataset has names, dates-of-birth, race and sex.
