The boxplot shows the distribution bias and variability of the blind organic QA recovery data of the entire schedule.
The plot also shows outliers and quartile ranges of the recovery data for every analyte in the schedule on one graph.
Extreme values have been "clipped" or removed from the plot and designated as such with a blue dot.
All data is provisional and may change if the OBSP deems necessary.
NOTE: Plots are presented as graphical images. It may be necessary to scroll through the image to see all the analytes in the schedule.
Note: If an analyte of interest is not seen in the method listing, there is no OBSP data available for that analyte
