WebSep 10, 2024 · Factorial designs aren't restricted to factors with only two levels. And the factors don't have to be continuous. For example, in this 2 x 3 x 4 factorial experiment, there are two levels of Speed, three levels of Temperature, and four levels of Material. You can run all combinations of the factor levels in 24 trials. Notice the Pattern column.
