In
addition, all participants results are statistically analysed and summarised in
a table, where
Method
: the
analytical method is displayed in the plot as a code
N
: number
of accepted results
Nr
: number
of rejected results; i.e. number of results outside mean ± 2.5 S.D.
mean,%
: the
average of all accepted results (N), as a percentage of the theoretical value
CV,%
: coefficient
of variation in %
Range,%
:
range of all results, in % of the theoretical value
