Question

Quizplus · Accepted Answer

The treatment effect refers to the change in the outcome resulting from variation in the treatment. It is the difference observed between the outcomes of the treatment group and the control group in a randomized controlled trial. The other options are incorrect. Selection bias refers to the bias introduced by the non-random assignment of units to treatment groups, random treatment refers to the random assignment of the treatment rather than a specific type of effect, and the effect of the treatment on the treated refers specifically to the effect of the treatment on those who actually receive it, rather than on the population as a whole.
