Suspended Sediment
Concentration |
|
|
|
|
Results
include determination of suspended sediment concentration. Target values are
determined gravimetrically during sample |
preparation.
Median percent differences are calculated using all submitted analyses by
participants for each sample class. |
Upper and
lower control limits are +/-3 f-pseudosigma from median, respectively.
F-pseudosigma = (Interquartile range)/1.349. |
Reported
laboratory results percent difference = (((Reported value - Target
value)/(Target value)) * 100). |
