The counterbalance standalone routine is available to use locally and online.
Everything in a PsychoPy® experiment needs a unique name. The name should contain only letters, numbers and underscores (no punctuation marks or spaces).
Choosing from Num. groups allows you to specify the number of groups and what their caps are. However, this cap is the same as for every group. The groups and caps you use here are only reflected for local use. For Pavlovia, you would need to set the number of groups and their caps via Shelf. Click here for an example on how to that.
Choosing from Condition file allows maximum flexibility in setting up groups. By using an excel spreadsheet, the probability of each group occuring, slots per group and any other additional parameters can be speficied. Note: This is currently not support for online studies
How many times you want the sampling to repeat. For example, if you put 2, the experiment will finish collecting all the required participant based on the counterbalance groups and then repeat the same procedure the second time.
If checked, this ends the experiment when all participants have filled all the counterbalance groups.
