Select a result and press [Details].

The name of the result and the variable for the mean value (in this

example SMN1) are shown under Details for each result (see

Section 4.5.1). The Mean value and the absolute (s +/-) and relative (s

rel) standard deviation are also shown above the list. The number of

individual results used for the calculation of the mean value is shown to

the right of the mean value. The number of the determination, the

sample size and the value including unit are shown in the list for each

result.
Results that could not be calculated are indicated with invalid and will

be ignored.
You can use [Result on/off] to exclude individual results from the

statistical calculations. The value for this result will then be indicated by

an *. With [Determination on/off] you can exclude all the results of a

Identification 1, Identification 2 and the Sample size of the
