WebJun 21, 2024 · 4. Factorial designs encourage a comprehensive approach to problem-solving. First, intuition leads many researchers to reduce the list of possible input variables before the experiment in order to simplify the experiment execution and analysis. This intuition is wrong. WebMay 10, 2013 · In factorial experiments, generally, the lower order effects are of more interest than the higher order interactions. Therefore, we assume that interest is in orthogonal estimation of main effects or orthogonal estimation of main effects and two-factor interactions.
