Screening Designs are a type of experimental design used when a large number of factors that may affect the process have been identified. The screening design is an initial design study that narrows the number of factors down to the few that have a significant effect. These significant factors are then investigated more closely with other design types.
Screening designs are Resolution III designs. They cannot separate interactions from main effects. There is a high risk that interactions will not be detected, and the results are open to misinterpretation. Refer to foldover designs for a possible solution.
