highly significantp = 7.00 ×10 −11
A multifactorial ANOVA of the three independent factors on OC concentration determined that all the factors (water content (WC), pH, and time) had highly significant effects ( p = 7.00 ×10 −11 ; p = 7.13 ×10 −5 and p = 7.97 × 10 −6 , respectively), but none of the interactions between the factors were statistically significant, indicating no combined effects on OC concentration in the extracts.
