Histogram for Time of Shift Beginning of shift -1, middle of shift -2, end of shift -3 Summary measures for selected variable: Time of shift Mean 2.002 Minimum 1.o Median 2.000 Maximum 3.0 Range 2.0 Sum 1185 Variance 0.533 Skewness -0.003Standard deviation 0.7301 Kurtosis -1.120 Count of Observations 592The mean (average) for time of shift that all command errors in the given sampling occurred is 2.002.Where 1 is the beginning of the shift, 2 is the middle of the shift, and 3 is the end of the shift.The maximum is 3, end of shift and the minimum was 1, beginning of shift.The assigned values, one, two and three total to the sum of 1185.The negative kurtosis value indicates that the distribution of the variable has than a normal distribution.The skewness value is very close to zero which indicates it has a symmetrical distribution.More Errors occurred in the middle of the shift than in the beginning or end of the shift.
