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.
