  1. Each F tests the simple effects of material within each level combination of the other effects shown. These tests are based on the linearly independent pairwise comparisons among the estimated marginal means
  2. a-b-c-d-e-f: There is no difference between the groups with the same
  3. Univariate Test; Tukey post-hoc Test
  4. *Significant p value at 0.05 level
