Selection bias: as mentioned above, if units with certain characteristics are more likely to be chosen into the treatment group, then we are facing the selection bias. Consistency of findings. However, we believe the treatment and control groups' outcome variable growing trends are not significantly different from each other (parallel trends assumption). Sociology Chapter 2 Test Flashcards | Quizlet Plan Development. Their relationship is like the graph below: Since the instrument variable is not directly correlated with the outcome variable, if changing the instrument variable induces changes in the outcome variable, it must be because of the treatment variable.
