Experimental Design. The Contractor shall select a rigorous experimental design that controls for confounding factors and other threats to the validity of the evaluation. The Contractor shall discuss the strengths and limitations of the chosen experimental design, including how it accounts for the effects of confounding factors in isolating impacts of the deployment. If using control/treatment groups, methods for recruiting participants of these groups, identifying the right type of participants, determining the appropriate sample size, and potential issues associated with sample size shall be discussed. Note that recruiting of participants is required only if the sites’ provided data and experimental designs are not sufficient to control for internal and external threats to validity of evaluation.
