The following ANOVA table corresponds to an experiment with two factors; 1) Time of Day

(morning, afternoon, or evening) and 2) Type of Teaching Method (lecture only or lecture with small group activities). The attention level (on a 0-10 scale) of college students during the morning, afternoon, or evening is measured in each of the teaching method conditions. This is a completely between-participants design. The scores for the five participants in each group follow.

Lecture Only/Morning: 8, 9, 9, 9, 10 Lecture Only/Afternoon: 5, 6, 7, 8, 9 Lecture Only/Evening: 5, 5, 6, 7, 7 Lecture-Small Group/Morning: 3, 4, 5, 6, 7 Lecture-Small Group/Afternoon: 5, 6, 6, 6, 7 Lecture-Small Group/Evening: 7, 7, 8, 9, 9 The sums of squares are provided in the following table. However, for practice, see if you can correctly calculate them by hand.

a. Construct the matrix showing the means in each cell and provide the factorial notation.

b. Complete the ANOVA Summary Table.

c. Are the Fobt significant at .05?

d. What conclusions can be drawn from the F-ratio?

e. What is the effect size and what does this mean?

f. Graph the means.
