Figure 3. — The left panel shows the scatter plot of the mean arm use of the two arms; the mean arm use of the right hand is plot along X-axis, and the left hand long the Y-axis. The first quadrant of the plot is partitioned into sectors of width 5° (ϕ) and the median value of the sector is calculated as ρ(ϕ). The points in sector ϕ = 35° are shown in violet. The grey contours in the background refer to the kernel density estimate of all points on the graph. The right panel shows the plot of ρ(ϕ) against ϕ. ρ(ϕ = 35°) is computed as the median distance of points from the origin (marked in red).
