I putting together a triage sieve study and want to track participants over a period of time, hence allocation by surname, but have been asked to think about different methods of allocation. I want something that is easy to reproduce across a number of groups and over a number of years hence the surname allocation. Allocation will be post an educational intervention with and without supporting documentation.
Yes, we did a trial of team-based learning vs. small-group learning in which students were assigned arbitrarily by last name (Willett LR et all Teach Learn Med 2011;23:28) but as a warning, the baseline test scores were slightly different.
Hi Laura, Thanks for your reply. I'm now leaning towards month of birth as my method of allocation. Glen.
