Hi,
Yes, this is described in the tutorials here and here
You can name the column “Group” or “List”, it doesn’t matter, PennController will use it to subset the table to the rows whose corresponding column contains only one of the possible values
Circulate the link to your experiment ending with server.py?withsquare=0
to some participants, with server.py?withsquare=1
to some other participants, and so on, until you get 10 submissions for each list
