Control vs. Polished	507.0	588.5	-81.52	50.12	10	10	2.300	27
Glazed vs. Polished	648.7	588.5	60.25	50.12	10	10	1.700	27
Test Results		Mean Diff.		95% CI of diff.		Significance
Control vs. Glazed		-141.8		-266.0 to -17.49		S
Control vs. Polished		-81.52		-205.8 to 42.76		ns
Glazed vs. Polished		60.25		-64.03 to 184.5		ns

(where q= studentized range statistic, DF= degree of freedom, S Indicates p ≤ 0.05 (significant), ns indicates p > 0.05 non significant)
