I have a problem which can be easily solved (I believe)- but I am unable to do so.
For my experiment, there are 4 practice items and 36 critical items following. I would like to randomize the trials – but I’d like to keep 4 practice item constant. I’d be great if I can randomize practice items within “Practice” items and 36 critical items within “Critical” items
When I tried Sequence( randomize(“Experiment”)), it randomized all 40 trials and I lost the practice sequence.
I also could not quite follow this: https://github.com/addrummond/ibex/blob/master/docs/manual.md#seq-randomize-and-shuffle
Could you help me with the code?
