Dear all,

Currently I am working on an online study in which randomization needs to take place at two different time points in the same experiment (two times random group assignment (first: one of three groups, second: one of two groups) in two different scripts). I am aware that there is the <expt> and <batch> function that can be used. Which one would you recommend? And how comprehensible are the group assignments given that they take place at two points?

Thank you and best regards,
Jessica
