Statistics on differences between IMU and goniometer behavior.

Activity	X	σ	t	p	Verified
Slow flexion	0.06	0.28	−1.56	0.33	Y
Normal flexion	−0.04	0.33	0.93	0.36	Y
Fast flexion	0.08	0.40	−1.63	0.20	Y
Slow walking	0.07	0.30	−1.61	0.26	Y
Normal walking	−0.06	0.39	0.89	0.28	Y

t represents the student statistic, and p is the related p-value.
