Abstract:

Ranked set sampling, a concept developed more than 50 years ago, aims at estimation of the mean of a population based on measurements of suitably selected ancillary sampling units. It turns out RSS provides a more efficient estimate of a population mean compared to the traditional simple random sample, even if the measurement of the ancillary variable is not good. In this paper, basics of RSS will be presented along with two novel applications. One of particular interest to EPA led to considerable savings in sampling costs dealing in the estimation of gasoline's Reid Vapor Pressure and resultant hydrocarbon emissions.
