9.1.1 Statistics

The statistics results of a sample series are shown in the statistics window .

This requires that the calculation formulas have been defined in the method

as statistics results ('statist.').
The statistics can comprise all results from 20 determinations. These

determinations must all be contained in the working memory.

As each determination can contain up to 50 results (including intermediate

results and common variables) this means that 1000 individual values are

theoretically possible.
