Question

Quizplus · Accepted Answer

Random assignment involves assigning participants to treatment groups randomly, such as by drawing names out of a hat, to ensure that the groups are equivalent at the start of the experiment. Therefore, Professor Hudgens is using random assignment. Matching involves assigning participants to groups based on their characteristics or attributes, which does not seem to be the case here. Experimental assignment and cross-sectioning are not appropriate terms for describing the method being used.
