Determine what type of situation this is and the type of DOE that was used effectively. Is it full factorial DOE? If so support your answer

In this research experiment, researchers couldn't use a full factorial design model because it wasn't practical. Full factorial designs are dependent upon researchers' testing all possible combinations of a set of factors, and because of randomization restrictions placed upon the study, randomizing all factors was not feasible. The research study consisted of hard to change factors, which would have been too costly and would have taken too much time to change the variable for full randomization. Therefore, researchers choose to use the split-plot design model to save time and money without losing any statistical data.

In the research study, the experiment consisted of three factors that presented 12 possible treatment combinations. The hard-to change factors were the temperature and solution, which placed randomization restrictions on the research ...
