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.
Mobile number portability (MNP) is a service that allows a cellphone or smartphone customer to change telecom carrier and keep the same phone number. The lack of number portability between wireless carriers has kept many consumers in India from changing cell phone service providers. Now that the infrastructure is finally in place, MNP will be available to all wireless customers by the end of January 2011.
