Hello!

I am having participants enter 10 items to create a list called itemsList.

I want to show all possible pairs of the 10 items and have participants rate on a slider bar (-1 to 1) how correlated they think each pair of items are. I believe there would be 45 pairs total (10 items, order doesn't matter).

So, I want to show 2 items at a time. The 45 pairs should be shown in random order.

Across participants, the item being on the left versus right of the screen (per pair) should be counterbalanced. 

How do I do this? 

Thanks in advance!
