RSD i

(Intermediate Precision)

Background  Some method developers have been submitting method validation manuscripts containing data for repeatability (RSDr) that is actually intermediate precision (RSDi).  Traditional RSDr data consists of replicate analysis to a common sample by a single analysis, using a single instrument, over a short duration (a day).  RSDi is an extension of RSDr in that multiple analysts using multiple instruments over multiple days analyze a common sample. Presumably the variability of a RSDi greater than the variability of a RSDr.
