Scenario:
In a team audit, one auditor had entered a sample to calculate positive indicators (e.g. 2/3 which is equal to 66% positive indicators) in the documentation information gathering step. Another auditor entered only the percentage of positive indicators, omitting the sampling (e.g. 20%).
The system provides the following warning:
How are these merged?
Firstly this ONLY affects audit where 2 auditors answered the SAME questions at the SAME site.
If both auditors provided sample it will add the numerators and denominators
e.g. 3/15 (20%) and 2/3(66%) will become (3+2)/(15+3) = 5/18 (28%)
If both auditors provided % we have to average the results
e.g. 20% and 66% will become (20% + 66%)/2 =43%
But in the scenario above one auditor provided a % and the other auditor provides a sample
We have to average the results of 20% and 2/3 (66%), but the system cannot guess how the user got to 20% (i.e. is it from 1/5 or 20/100?)
The result is that it will discard the sample and calculate the average only based only on the %
In this example = (20% + 66%)/2 =43%
