Users can optionally select to see some or all of the following statistics for their data.




A Non Detect multiplier can be applied (the value used in calculations where results are ND).


The Geometric Average and the Geometric Standard Deviation are the same as a "Log Average" and "Log Standard Deviation".


The 95th Percentile is not Reported in the statistics.  Users can choose to use a standard formula based on the average the standard deviation (or the logs of them), depending on which is considered the most accurate for the data.  Alternatively an export to the USEPA package "ProUCL" is available, which will determine the most accurate 95th percentile value available for the specific dataset.
