9.3 A population consisting of 2500 elements is divided into 10 strata, each containing 50 large units composed of five elements. The analysis of variance of the population for an item is as follows, on an element basis. df ms Between strata 30.6 Between large units within strata 490 3.0 Between elements within large units 2000 1.6 248 SAMPLING TECHNIQUES Ignoring the fpc, is the relative precision of the large to the small unit greater with simple random sampling than with stratified random sampling (proportional allocation)
