Question

Which statement about random assignment is TRUE? A. The purpose of random assignment is to ensure that participants are unaware of the experimenter's hypothesis. B. The purpose of random assignment is to minimize differences in participants' characteristics across all conditions of an experiment. C. The purpose of random assignment is to allow the experimenter to generalize results to the relevant population. D. All of these statements are true.

Answer 1

The purpose of random assignment is to minimize differences in participants' characteristics across all conditions of an experiment.

Step-by-step explanation:

The purpose of random assignment is to minimize differences in participants' characteristics across all conditions of an experiment. Random assignment is critical for sound experimental design as it makes it unlikely that there are systematic differences between the groups. By randomly assigning participants, we can assume that any differences observed between experimental and control groups result from the manipulation of the independent variable.
