Trouble comparing variables in SPSS to one set of rules

#1
Hi guys!

I am a little puzzled. :confused::confused:

I am carrying out research on cyclists perceived benefits of the supplements they take and comparing them to what is scientifically proven.

So far I have inserted all my data into SPSS and I have grouped all the variables accordingly.

The problem I am having is that I do not know how to include the non-variable (what is scientifically proven) within the data set nor do I know how to then compare it to my variables.
