Table 2.2-4: One-way analysis of variance showing the effect of soil compartment on the discriminant scores for the linear discriminant function 1 (LD 1) and the linear discriminant function 2 (LD2). TukeyHSD post -hoc test was applied to reveal significant differences between each soil compartment. Degrees of freedom (df), F-values and significance level (p) are shown for soil compartment.
