Quizplus · Accepted Answer

An interaction occurs when the effect of one variable (in this case, the teaching method) depends on the level of another variable (here, the age group of the students). If the new method is only effective for the youngest age group, this indicates that the effectiveness of the teaching method interacts with the age of the students.
