Example 12.8. A Three-Factor Factorial Experiment A study was
designed to evaluate the effect of wind speed and ambient temperature on
scale accuracy. The accuracy is measured by loading a standard weight
on the scale and recording the difference from the standard value. A 3

factorial experiment was planned. The data listed in Table 12.18 were
obtained.
