1. In 2-way ANOVA, each independent variable investigated could have two or more different treatments or ______________.
2. A Two-Way ANOVA Summary Table is shown below.
The critical value for the F test using \\alpha = 0.05, d.f.N. = 2, and d.f.D = 27 is 3.35. Then,
a. only the null hypothesis concerning Factor A should be rejected.
b. only the null hypothesis concerning Factor B should be rejected.
c. only the null hypothesis concerning Factor A and the Interaction (AxB) effect should be rejected.
d. all of the null hypotheses should be accepted.
| Source | SS | d.f. | MS | F |
| Factor A | 9.42 | 2 | 4.71 | 2.77 |
| Factor B | 15.10 | 2 | 7.55 | 4.44 |
| Interaction A x B | 10.34 | 4 | 2.58 | 1.52 |
| Within (error) | 45.90 | 27 | 1.7 | |
| Total | 80.75 | 35 |
Solution
1. or conditions.
2.
Only null hypothesis concernng factor Bshould be rejected becuase its statistics value is greater than critical value. Option b is correct.
