  • Sum - sum of all observations
  • Min - smallest value of the data
  • 1st quartile - 25% of the data are less than or equal to this value
  • Median - 50% of the data are less than or equal to this value
  • 3rd quartile - 75% of the data are less than or equal to this value
  • Max - largest value of the data
  • Range - different between the largest and smallest value of the data
  • Mean 95% CI-L and Mean 95% CI-U - lower and upper confidence interval limits for the mean
  • Sigma 95% CI-L and Mean 95% CI-U - lower and upper confidence interval limits for the standard deviation
  • Median 95% CI-L and Mean 95% CI-U - lower and upper confidence interval limits for the median
