Question:
Consider the following sample data for a two-factor ANOVA analysis. There are two levels (heavy and light) of factor A (weight), and three levels (small, medium, and large) of factor B (size). For each combination of size and weight, there are three observations.
Compute an ANOVA with statistical software, and use the .05 significance level to answer the following questions.
a. Is there a difference in the Size means?
b. Is there a difference in the Weight means?
c. Is there a significant interaction between Weight andSize?
