Latin square

[g-porta]

Hi!
My experiment uses a Latin square design. I created each list, and now I want the code to assign each list to a participant. I tried fully randomising this part, but the results are too random, and I'd be force to delate some data.

Is there a way of alternating between four lists automatically?

Thanks!

Hi @g-porta,

How are you hosting your experiment online? (This is a problem that has to be solved on the hosting side.)

Hi!

I'm hosting in it on Jatos.

I tried to split the lists into four components using jatos.startNextComponent , but I couldn't get it to work. I tried modifying the template they put online (Randomize Tasks Between Workers) but I couldn't get that one to work either.

I tried with the batch function, but I still get some kind of error.

function initBatchConditions() {
      if (!jatos.batchSession.defined("/trials")) {
        jatos.batchSession.set("trials", 0).fail(initBatchConditions);
      }
      
      trials = jatos.batchSession.get("trials")
      jatos.batchSession.set("trials", trials + 1 ).fail(initBatchConditions); // If it fails: try again
        console.log(jatos.batchSession.getAll());
        console.log(trials % groups.length);
      return trials;
    }

I don't really know where to go from here...

What would you recommend?

Thanks!

Hi @g-porta, did you figure out a fix? I am stuck on this too.
