How to assign participants uniformly across conditions with multiple sets of stimuli in a single experiment file?

If this template helps then use it. If not then just delete and start from scratch.

What are you trying to achieve?:

Hi there, in my experiment, there are 195 possible conditions in a single experiment file. I’d like participants to be assigned in such way that every condition would have at least 1 participant. How can I achieve that? Does Mory Scater app work for this?

Thanks!

Are you running this online?

My app could be used to select different rows from a spreadsheet using the participant number, e.g. useRows=str(int(expInfo[‘participant’]))+”:”*str(int(expInfo[‘participant’]+1)

However, it can’t adjust for non completions. I have ideas about how to deal with that but I’m waiting until I either need it myself or someone commissions me to rewrite my app

I’ve now written an app to deal with non completions.

It can also assign participants randomly to any number of different groups (as opposed to having to use the participant number which would make the assignment consecutive).

Thank you so much!
