Comparison of mean value for maximum fracture resistance to oblique forces between and within the groups with one-way ANOVA

Groups	Sum of squares	df	Mean square	F	P
Between groups	205614.475	3	68538.158	32.381	0.000
Within groups	76198.500	36	2116.625
Total	281812.975	39

Df=Degree of freedom, F=Fisher ratio, Between groups=Designates variance within A1A2, A1B1, A1B2, A2B1, A2B2, and B1B2, Within groups=Means the variance calculated among the samples within any one group such as A1 or A2 or B1 or B2
