ANOVA for oil degradation % in the L16 (45) orthogonal array experiment
Factor | SS | DOF | F | P-value |
---|---|---|---|---|
Salinity | 883.076 | 3 | 3.28 | 0.03 |
pH | 3399.379 | 3 | 12.62 | 0.00 |
Temperature | 4669.017 | 3 | 17.33 | 0.00 |
FeSO4 7H2O | 403.961 | 3 | 1.50 | 0.23 |
NH4Cl | 212.793 | 3 | 0.79 | 0.51 |
SS=sum of squares of deviation, DOF = degree of freedom, F= a ratio of the mean of the squared deviation to the mean of squared error
