The two-way ANOVA computed illustrates that the number of treatments in this experiment is 36.
From the information given, it was stated that in the ANOVA, there are 4 levels for factor A, 3 levels for factor B, and 3 observations within each of the 12 factor combinations.
Therefore, the number of treatments in this experiment will be calculated thus:
= Number of levels for A × Number of levels for B × Number of observations
= 4 × 3 × 3
= 36
In conclusion, the number of treatments is 36.
