Cumulative Time Series Charts and Statistical Summaries
Analyzed between January 2013* to October 2018

The time series charts provided in this section have a different symbol for each level. The recoveries shown on the chart do not include false positive data. A LOWESS, LOcally WEighted Scatterplot Smoothing, (Cleveland and McGill 1984b, Cleveland, 1985) line is used to help observe any patterns of recovery over time.

*Due to the size of the dataset, methods indicated with an astrik have a different start date than indicated above

NOTE: Charts are presented as graphical images. Use the back button on your browser to return to analyte choices. If the graphic is fit to one page and appears in minuscule font you need to perform the following action:

Tools/Internet Options/Advanced - uncheck "Enable Automatic Image Resizing"/Apply/OK then refresh.

Statistical Summaries
There are two tables provided at the bottom of every time series chart that show statistical summaries.
Statistics for the Plotted Points
Description of the OBSP QA recoveries grouped by concentration level. The statistics in the table: mean, median, standard deviation and F-pseudosigma define bias and variability of the OBSP recoveries.
Miscellaneous Statistics for the Samples
Counts (N) of a variety of items.
Plotted - This number equals the total number in the above table.
Estimated Values - There are a number of reasons the laboratory will estimate (E) a result. If there are 100% of the results estimated the analyte is identified as a permanently estimated compound (analyte name in time series chart will be red).
Deleted Values - The laboratory may delete an entire sample or a single analyte for a number of reasons.
Spiked, Censored - A term for those samples that were spiked and correctly reported as less than a reporting level (possibly a raised reporting level) - the expected concentration was at a lower concentration than the censored result provided by the laboratory.
Spiked - The number of times the OBSP has submitted this analyte to the NWQL.
False Negative - The number of times the laboratory reports this analyte as not present in the sample when it is there. If the percentage is greater than 20% we include the occurrence in the OBSP Summaries (Internal access only)
Not Spiked - The number of times the OBSP has submitted a sample to the appropriate method, without this analyte.
False Positive - The number of times the laboratory reports this analyte as present when it is not in the sample.

An example of the statistical summary table is not provided with the time series chart example below. Please use the tables below the example to view time series charts and their respective statistical summaries by clicking on an analyte of your choice.

Data Provisional: Subject to change.

These charts are presented in percent recovery and Organized Numerically by NWQL Schedule (individual lab codes are grouped at the end).
