Is variables instantiation just a check? OR must it be done if I want (say) 50 data sets?
I notice that I do Instantiation and then the next time I edit the question, the data set seems to have disappeared.
Is the Instantiation to create a data set for the students' quiz?, OR does it just give me a temporary long list of answers so I can see the results are reasonable.
I know I am repeating myself, but Moodle gives no help on what Check variables instantiation really means.
