In Table II, the standard deviation is proportional to the average and the %RSD is unchanged. Good documentation requires reporting the sample size, average, and standard deviation with the %RSD. The %RSD is misleading when used with data that are expressed as a percentage such as percent recovery. The standard deviation of the data is already in percent. To then find the %RSD is to make the results dependent on the random variation of the average. This defeats the original purpose of estimating the variation of the data values.
Interoperability (pronounced IHN-tuhr-AHP-uhr-uh-BIHL-ih-tee) is the ability of a system or a product to work with other systems or products without special effort on the part of the customer.
The Open System Interconnection (OSI) protocol suite is comprised of numerous standard protocols that are based on the OSI reference model. These protocols are part of an international program to develop data-networking protocols and other standards that facilitate multivendor equipment interoperability. The OSI program grew out of a need for international networking standards and is designed to facilitate communication between hardware and software systems despite differences in underlying architectures.
