Table 6: _Cont._These ranges were selected based on the variance of the number of defects. Table 7 presents the results of the analysis. The entire model explains 78% of the total variance in the number of defects, and also shows which of the factors differentiate the number of defects the most. The \(p\)-value for the F test in the model indicates the statistical significance of the discrimination.
