Quizplus · Accepted Answer

The two important considerations during the difference-in-difference approach are representativeness and leakages. Representativeness refers to the extent to which the treatment and control groups are similar in their characteristics and composition, which is necessary for a valid comparison. Leakages refer to any spillover effects or external factors that may affect the treatment group but not the control group, which can bias the results. Therefore, C is the best choice as it accurately describes the important considerations in this approach.
