How is the median value of the reporting limit for nondetect samples computed when there is an even number of samples?
The median always works out unambiguously when the number of data is odd. When there is an even number of data, there is more than one definition of the median in common use. The definition we use is that the median is the smallest value that divides the data into two equal parts. So for example the set of numbers {0, 0.5 , 1, 2, 2, 5} would have 1 as its median.
