Set Custom Screening Statistics

SADA Version 3 allows the user to select the statistical approach for calculating screening values.

From the Custom Analysis menu, select Configure Custom Analysis and then Set Screening Statistics. SADA opens the following window.

Select the desired statistical approach and press the OK button. The different approaches are defined as follows:

• Maximum Value – the maximum concentration, detected or nondetected, for normal or lognormal distribution

• Maximum Detected Value – the maximum detected concentration for normal or lognormal distribution

• UCL95 – the 95% upper confidence limit on the mean for normal or lognormal distribution

• Mean – the average concentration over all values for normal or lognormal distribution

Note: For screening calculations, the maximum detected value is the default option.
