PPT-Randomized Evaluation:

StarttoFinish Jon Robinson UCSC Course Overview Why evaluate What is evaluation Outcomes indicators and measuring impact Impact evaluation why randomize. Randomiza tion if done properly can keep study groups as similar as possible at the outset so that the investigators can isolate and quantify the effect of the interventions they are studying No other study design gives us the power to balance unkno Adversarial Environments.
