What are the limitations of a two-way ANOVA?
Posted May 19, 2022
Answer
These are the limitations found in a two-way ANOVA:
- It becomes difficult to maintain homogeneity of the blocks if the number of treatments is large enough.
- The technique can be challenging and time-consuming.
- In order to get accurate results, a missing value cannot be ignored. Certain adjustments must be made in the analysis after replacing the missing value with some function of the existing values.
- Analysis becomes increasingly more complex and interpretation more difficult when the number of the factors are increased in a study.
