The difference between the medians of each behaviorwas then tested with a Mann-Whitney U test. Furthermore, the personalities of the chimpanzees were analyzed, byfirst plotting X-Y graphs of the median, kurtosis, skewness, and IQR.Afterward, χ2 tests were performed on the slopes, todetermineif there were any significant differences in the chimpanzee’s personalities.Additionally, behavioral diversity was calculated and compared with χ2 tests. Based on these tests, it was not possible to conclude whether the sleep meditation causedachange in behavior in the enrichmenttestperiod.
