14.5.1.1 Factors and Levels
When executing a full factorial experiment, a response is
obtained for all possible combinations of the experiment.
Because of the large number of possible combinations in full
factorial experiments, two-level factorial experiments are fre-
quently utilized. Experiment 1 was a two-factor, two-level
experiment. As described in Table 14.1, a total of four trials were
needed to address all assigned combinations of the factor levels.
The specic situations to which a DOE is applied will affect how factors and levels are chosen.
Factor levels also can ...
