Figure 4

Boxplot of the stereoacuity of the four groups. The line perpendicular to the whisker below the box represents the minimum value; the lower edge of the box represents the first quartile; the thick solid line is the median; the upper edge of the box represents the third quartile; the line perpendicular to the whisker above the box represents the maximum value. Circles and star represent outliers.
