So, hypothesis testing proceeds similar to the techniques we learned for the one-way ANOVA. The two differences are the calculation of the error variance (MSE) and a calculation of the effect of the blocking factor (MSB).

• The reason why this ANOVA is significant whereas the one in question 2 is not is because the variance within groups is much smaller (note the standard deviations in each group compared to question 2 in the table of descriptives).

Step 1 generates a transformed data yij (λ). Apply ANOVA to the new data and obtain SSE . Because SSE depends on λ, it is denoted by SSE (λ). • Repeat 1 and 2 for various λ in an interval, e.g., [-2,2], and record SSE (λ) 3 Find λ0 which minimizes SSE (λ) and pick up a meaningful λ in the neighborhood of λ0.

On the Fisher’s principles, a classical experimental design (e.g. one-way ANOVA, Latin square design (LSD), 2-level factorial design, factional factorial design, and so on) is a powerful methodology in order to explain causal mechanisms between independent variables and response variable by means of the identification of variation of data.

The power of the test also is reduced if the assumption of NID(0, σ2) is violated. Violation of the assumption NID(0, σ2) with the fixed model is usually of little consequence because ANOVA is a very robust technique. Violation of the basic assumptions of ANOVA can be investigated by observing plots of the residuals.
