An evaluation is a systematic and objective examination concerning the relevance, effectiveness, efficiency, impact and sustainabilities of activities in the light of specified objectives. [2] The idea in evaluating projects is to isolate errors in order to avoid repeating them and to underline and promote the successful mechanisms for current ...
The ATE measures the difference in mean (average) outcomes between units assigned to the treatment and units assigned to the control.

The core question of comparative effectiveness research is which treatment works best, for whom, and under what circumstances. [ 1 ]
