The XLS sheet below calculates your measurement uncertainty (MU).

You have to:

0. define/introduce your measurement "unit";

1. determine your uncertainty function

introduce 15 measurement results of the routine samples (6 low and 9 high contents) analysed twice;

2. calculate your bias

introduce up to 7 replicate measurement results of the reference material (RM),

introduce the reference value and associated expanded uncertainty (k=2) of the RM;

3. estimate your MU

introduce the measurement result value.

Note:

Microsoft does not allow to copy&paste cells into the online spreadsheet.

You have to type in all values one-by-one, in the yellow cell ONLY.

Your values will not be saved. The spreadsheet will be reset (= all introduced values deleted) each time you leave or refresh this page.
