Cumulative Time Series Charts and Statistical Summaries
January 2001 to September 2006

Time Series Charts
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.

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 schedule, without this analyte.
False Positive - The number of times the laboratory reports this analyte as present when it is not in the sample.
OBSP plans on providing more False positive and false negative information in the future. 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.

Example of a Time Series Chart:

Example of a Time Series Chart
HIGHA concentration range determined by OBSP to assess the high end of the calibration range of the method.
LOWA concentration range determined by OBSP to assess the low end of the calibration range of the method.
MEDIUM A concentration range determined by OBSP to assess the middle of the calibration range of the method.
ULTRA-LOWA concentration range determined by OBSP to assess the lowest end of the calibration range of the method.

These charts are presented in percent recovery and Organized Numerically by NWQL Schedule (individual lab codes are grouped at the end).
Estimated Analytes are designated with an (E) after the analyte name in the list below.

The charts and data that you might secure from this U.S. Geological Survey (USGS) web page (identified as "OBSP") have not received official USGS approval and as such are provisional and subject to revision. The charts and data are released on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from its authorized or unauthorized use.
