The tasks are very similar but not identical to avoid a learning effect and I would like to randomize the way both the videos and the tasks appear. If the same task always follows the same video, the differences in performance could be attributed to difference in the tasks themselves (we piloted the difficulty of the tasks to check that they were similar, but still…)
The aim would be that each person sees one of the four videos, then perform one of the four tasks, continue with a second video and a second task, until completing the four videos and the four tasks.
The challenge is how to setup a flow for a design like this one, ensuring that the order of the videos and the order of the tasks are randomized without repeating.
Any idea on how to do it?
