Table 4.
Analysis of variance for the model of log VOCs on the fixed effect of activity and the random effects of salon and shift within salon with the Kenward-Roger degrees of freedom method.
| SS | MS | Num df | Den df | F value | p-value | |
|---|---|---|---|---|---|---|
| Activity | 53.7 | 10.7 | 5 | 1,136 | 4.052 | 0.001 |
These are Type III sums of squares, which is the sum of squares given all other effects in the model. SS, sum of squares; MS, mean squares; Num df, numerator degrees of freedom; Den df, denominator degrees of freedom.
