Results of Student’s t-test of the Two Mean β-hCG MoM Values

	Sample	t	df	p	p Variance
B-hCG MoM	104	0.629	206	0.530	0.018

Notes: t – Student’s t-distribution. df – number of degrees of freedom. p – (p-value) test probability. p variance – (p-variance) – test probability for variance (Levene’s test).
