I am trying to figure out how to randomize participants in a 2:1 ratio to
treatment and control. I would also like there to be equal numbers of men
and women in the treatment and control groups. Any ideas on how to go about
doing this?
This is pretty tough to do in real-time (i.e. when a participant is being
registered) and make sure that there is an exact number of participants in
each group. Some options:
Use a random number in a hidden value when a participant is being
registered to group them into treatment and control (i.e. if the random
number is less than 0.333, they are control otherwise they are in
treatment). This method assumes there is an equal number of women and men
being registered and it doesn't guarantee the exact breakdowwn you want (it
will be approximately correct, but it will be random).
Once all your participants are registered, download the data into
Excel and then manually randomize them and then use the Case Importer to
update the cases back on CommCareHQ.
