Answer 1

random assignment. (Researchers try to create groups that, before an experiment begins, are similar with respect to the dependent variable. The most common way of achieving this goal is through random assignment. With the help of random assignment, we can make sure that the treatment groups are similar to each other. It is also to be made sure that the treatment groups are also similar or nearly equivalent to the control groups. This is to make sure that we do not introduce any kind of bias in the study.)
