Important Note

For the remaining items you are to create an APA styled results presentation. This will include a table of results, and written inference and interpretation. If you are unclear about APA styled tables, review carefully the examples provided in the linked Word document on the Course Index. Each APA presentation is worth 10 points (unless specified otherwise)

6. One study experimented with the order of cognitive organizers that structure material for learners. A group of 30 students was randomly split into three groups of 10 each. Group 1 received organizing material before studying instructional materials on mathematics; group 2 received the organizing material after studying mathematics; group 3 received mathematics material, but received no organizing material. On a ten-item test on mathematics covered during the experiment, the scores presented below were earned by students in the three conditions. Is there any evidence that organizers influenced student achievement in mathematics? Use ANOVA for this analysis. (10 points)

Group 1 (Organizer prior to instruction)	Group 2 (Organizer after instruction)	Group 3 (No organizer)
5	7	5
6	5	4
7	3	6
7	6	2
9	6	2
7	3	2
6	3	6
10	8	4
6	4	3
7	2	5

Note. Higher scores indicate better achievement.
