Box-and-whisker plots (Becker et al. 1998 [41]) of efficiency tests (100 observations per box) for seven robot group sizes in the maze arena. The boxes represent the interquartile ranges of the data, while the horizontal bars inside the boxes indicate the median values. The whiskers extend to the most extreme data points within 1.5 of the interquartile range from each box. The empty circles represent outliers.
