Answer:
D. To produce treatment groups with similar characteristics.
Step-by-step explanation:
Random Assignment is the process of classifying the participants into groups. A group such as the one in the question could be classified into the treatment or experimental groups and the placebo groups. The importance of random assignment is to ensure that any differences in the group is as a result of the treatment and not any other factor. Therefore the participants must have similar characteristics so that any observed differences in the experiment, can be attributed to the treatment.
Random selection is used by experimenters in research work for the purpose of ensuring that all members of the group have an equal chance of being selected as participants of the study. In this instance, the researcher is trying to ensure that the number of participants in the study is a true representation of the entire population.
