According to this psychological principle, recall of information will be best if the testing conditions are the same as the conditions that existed at the time of learning. In this experiment, students are given a lecture on an unfamiliar topic and one week later, they are tested on the lecture material. Some students receive the lecture in the small classroom and some in the large classroom. At the time of the test, one- half of the students from each group is tested in the small classroom and another half is tested in the large classroom. Thus, the experiment involves four groups. The score for each participant is the number of correct answers on the test. Do these data indicate that the size of the lecture room and/or testing room has a signicant effect on test performance? Test at 0.05 level of signicance. Provide a conclusion.
