Question
For 2 3 factorial design, with three replicates of each factorial combination, the following data was given by the software: Contrast for A: 148 Contract
For 23 factorial design, with three replicates of each factorial combination, the following data was given by the software:
Contrast for A: 148
Contract for B: 685
Contrast for BC: -830
Sum of squares for error: 21000
Write the generic equation that estimates Contrast for A.
Write the equations that relate the contrast to the sum of squares; identify the degrees of freedom for Effect A, Effect B, Interaction BC, and error.
Using the degrees of freedom, estimate the mean sum of squares and F value.
Are the effect A, B and BC significant with 1% alpha?
