Randomized evaluations are field experiments involving the assignment of subjects randomly to one of two groups: one, the treatment group, which is receiving the policy intervention being evaluated, and two, the control group, which is in status-quo.
The results of the trial are used to answer questions about effectiveness of an intervention, and can prevent inefficient allocation of resources to programs that might not be effective.
This section covers the key principles of study design to guide researchers on best-practices in conducting field evaluations.
