The middle line represents the median, the + sign, the mean, the lower and upper boundaries of the boxes, the 25^th and 75^th percentiles, the whiskers, the 5^th and 95^th percentiles, and the dots, the outliers. As some data were missing, the number of data points is reported.

Figure 2. Box-plot of self-reported listening ability scores for the Neuro One and the Neuro 2 sound processors for the three factors, combined for adults and children. The middle line represents the median, the + sign, the mean, the lower and upper boundaries of the boxes, the 25^th and 75^th percentiles, the whiskers, the 5^th and 95^th percentiles, and the dots, the outliers. As some data were missing, the number of data points is reported.
