Index of test	F	Factor				Critical value
Index of test	F	A	B	C	D	Critical value

Slump	F₁	32.662	5.94	9.862	0.602	F_0.01 (3, 3) = 29.5
Apparent density	F₂	9.173	11.577	6.018	0.584	F_0.05 (3, 3) = 9.28
7 days’ tube crushing strength	F₃	9.596	7.626	5.41	0.353	F_0.1 (3, 3) = 5.39
28 days’ tube crushing strength	F₄	13.416	6.832	5.694	0.447

Note. When F > F_0.01, the influence of factors is significant, and the factor is marked as ; when F > F_0.05, the factor is marked as ; when F > F_0.1, the factor is marked as .
