Case-control classifies based on outcome and looks back in time for exposure.
Blocked random allocation - ANSWER Used to ensure that at any given point in
time, the groups will be similar or equal in size. I.e. ABBA, BAAB, ABAB
cluster randomization - ANSWER groups of patients are randomized rather than
the individual patients, I.e. entire hospitals or clinics are randomized to an
intervention
, Stratified randomization - ANSWER individuals are grouped into strata (I.e.
