Question

Quizplus · Accepted Answer

A random-assignment experiment is the most desirable research design to measure changes in two groups where one receives a "treatment." This is because the randomization process helps to ensure that any differences in outcomes between the groups are due to the treatment and not other confounding factors. Random sampling, sex vs. gender, and stereotypical experiments are not relevant to measuring changes in two groups with a treatment.
