FIG. 2. Boxplots of groups with no sonar exposure, all groups that cooccurred with sonar, and groups that exhibited a behavioral response to the sonar for (a) rates of behavior change (in minutes) and (b) ratios of the rate of behavioral change over duration of observation. The center line of each box indicates the median value, while the edges are the 25th and 75th percentiles and the whiskers cover about 99% of the data. Outliers are indicated by crosses.
