Random assignment of volunteers should result in comparable experimental groups.

Question

Quizplus · Accepted Answer

Random assignment is a method of assigning participants to different experimental groups, with the intention of creating groups that are comparable in terms of relevant variables such as age, gender, and baseline measures of the outcome variable. When done properly, random assignment should ensure that any differences between the groups are due to chance alone, rather than systematic differences in participant characteristics.
