[solved] Counterbalancing
I am programming a questionnaire to be used on an android mobile phone. There are three blocks of questions and I would like the blocks to be counterbalanced. I have found the counterbalancing information on the site, however my participants will fill the questionnaire in multiple times and so a system whereby an odd/even participant number always produces a particular counterbalanced order isn't appropriate for my study. I've searched the site but I can't find anything. If anybody knows a way to do this I would be very grateful.
Thanks a lot for your help!

Hi Jayne,
You'll have to provide a bit more information. Exactly how and based on what do you want to counterbalance? Based on the number of times that the experiment has been started? Or some session id that the participants enter? And is the counterbalancing procedure the same for all participants?
Cheers,

The counterbalancing procedure would be the same for all participants and would be based on the number of times the experiment has been started. There are three blocks of questions (block A, block B, block C). Ideally I would like it to sequentially run through the six orders: ABC, BCA, CAB, ACB, BAC, CBA then back to ABC for each participant (it's a long study so they fill the short questionnaire out several times). If that is too difficult it would be okay if the blocks were randomised. Essentially the participant fills the questionnaire many times and I just don't want it to be in the exact same order every time.
I've found the inline script that does this now, thanks a lot for your help
