Fig. 5: Variability of Gait Features.

Distribution of the relative mean error across 50, 100 and 128 Hz sampling rates per calculated feature. The solid line represents the median value; the box limits show the interquartile range (IQR) from the first (Q1) to third (Q3) quartiles; the whiskers extend to the furthest data point within Q1–1.5*IQR (bottom) and Q3 + 1.5*IQR (top).
