: Czy przypadkiem nie chodzi o "pomiar w skali logarytmicznej"?

Dziękuję Sławomirze. Dokładnie. Uważam, że to jest to samo co moje wyrażenie. Pomiar sam w sobie nie jest w skali logarytmicznej. Bierze się pomiar i potem się go logarytmuje.

In-house repeatability standard deviation and in-house reproducibility standard deviation are important performance characteristics of any measurement method. They describe precision of the alternative method under in-house repeatability conditions and in-house reproducibility conditions. One (food) item is selected per (food) category for the determination of the in-house repeatability standard deviation and the in-house reproducibility standard deviation. If the artificially contaminated (food) item is sufficiently stable, microbiologically, tests are conducted on eight different days by three or more technicians. No technician shall conduct tests on more than three days. However, if only two technicians are available, then each technician shall conduct tests on four days. If only one technician is available, this technician shall conduct all tests, but the method is then validated only for this technician. On each day, one of the technicians performs tests on five replicates using the alternative method, yielding a total of 8 × 5 = 40 tests. In addition, five replicate tests are performed using the reference method on day one as a control. The in-house repeatability standard deviation is calculated as shown by Formula (5): sr ,in-house =

Discussion
(log10A + log10B + log10C + log10D + log10E)/5
Interestingly, by properties of logs, this is the same as the log of the product, that is, [log10(ABCDE)]/5.
Actually, it makes more sense to take the average of the measurements and then take the log10 of the average.
