A researcher plans to test a fall-prevention intervention by gathering data in 10 sites, 5 of which will be implementing the intervention. If the 5 of the 10 sites are assigned at random to the intervention, what type of randomization is in use? A. Simple randomization B. Cluster randomization C. Urn randomization D. Complete randomization
Homework Answers
ANSWER.
B. If a researcher plan to test a fall prevention intervention by gather data in 10 sites
and 5 of the 10 sites are assigned at random to the intervention then the type of
randomization is in use is Cluster randomization.
Cluster randomization used at the level of social units,hospitals,multiple researchers,
sites etc.
