Concept explainers
The next table gives data for a 2 × 2 factorial experiment with two observations per factor-level combination.
Identify the treatments for this experiment. Calculate and plot the treatment
Use the computational formulas in Appendix C to create an ANOVA table for this experiment.
Test to determine whether the treatment means differ at the α = .05 level of significance. Does the test support your visual interpretation from part a?
Does the result of the test in part b warrant a test for interaction between the two factors? If so. perform it using α = .05.
Do the results of the previous tests warrant tests of the two factor main effects? If so, perform them using α = .05. Yes.
Interpret the results of the tests. Do they support your visual interpretation from part a?
Given the results of your tests, which pairs of means, if any, should be compared?
