Box Plots for OBSP Samples
January 2002 to December 2007

Extreme values have been "clipped" or removed from the plot and designated as such with a blue dot. OBSP Box Plots Organized Numerically by NWQL Schedule(individual lab codes are grouped at the end).
*Due to the size of the dataset, schedules indicated with an astrik have a different start date.
The following abbreviations and formats apply to all of the posted charts:
‹RLA range with expected concentration less than the reporting level
LowerA range with the expected concentration in the lower end of the calibration range
UpperA range with the expected concentration in the upper end of the calibration range
NCount of samples in the specified range
MedMedian recovery of samples in the specified range
FPsigF-pseudosigma of samples in the specified range
MeanAverage recovery of samples in the specified range
StdStandard deviation of samples in the specified range
E CodesPercent of samples in the specified range that are estimated

These plots are presented in percent recovery.
