What is the "Uncertainty Factor"?

Uncertainty factors are based on log-transformation

The Eurachem working group on Uncertainty from Sampling has published a new Information Leaflet introducing the idea of the "uncertainty factor". The leaflet, which was developed jointly with the RSC Analytical methods Committee, explains how an uncertainty factor can be used to provide a convenient and realistic uncertainty interval in circumstances where a simple symmetric interval is not suitable.
