Figure 2. WDT for each condition (“Headset” and “No Headset”) and background (quiet or noise). Individual data points are shown by white circles. The horizontal lines denote the medians. Boxes enclose the interquartile range, and whiskers show the upper and lower quartiles. Data points above or below the upper or lower quartiles, respectively, are outliers.
