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
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.
