Common use of Experimental Design Clause in Contracts

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. The Contractor shall refine the MEP evaluation plans and submit for review to the COR and other USDOT representatives, and revise based on comments received. The Contractor shall submit to the COR, the Revised Plans and corresponding Comment Resolution Reports that document how each substantive comment was resolved. The COR, in consultation with the Contractor shall determine if a meeting is necessary to discuss any of the comments (depending on the nature and quantity of the comments). Upon the COR’s approval of the Comment Resolution Reports, the Contractor shall make revisions (as per the Reports) and submit final versions of the MEP evaluation plans.
