( relevant section)ĪQ104.01.05. This experiment involves two kinds of non-random sampling: (1) Subjects are not randomly sampled from some specified population and (2) Subjects are not randomly assigned to conditions. At the end of the semester 12 subjects volunteer and are assigned to the spaced-practice condition. At the beginning of the semester 12 subjects volunteer and are assigned to the massed-practice condition. Subjects volunteer from an introductory psychology class. A study is conducted to determine whether people learn better with spaced or massed practice.
