This problem is a special case of the classical occupancy problem. If you conduct simple random sampling with replacement, choosing n objects from a population of N, then the number K of sampled items has a classical occupancy distribution with probability mass function: P ( K = k N, n) = ( N) k ⋅ S ( n, k) …
WebSep 28, 2015 · In such situation, according to the interest variable, the population is divided into homogeneous subgroups. The strata should be mutually exclusive. To get a sample, SRSWR or SRSWOR can be applied within each stratum. In addition, if inside each stratum is homogeneous and there are serious gaps between strata, StS is more efficient than … WebSimple random sampling without replacement (srswor) of size nis the probability sampling design for which a xed number of nunits are selected from a population of N units without replacement such that every possible sample of nunits has equal probability of being selected. A resulting sample is called a simple random sample or srs.
Websample of n units in SRSWOR is ( ( )! NN 1 N n 1 n = n N 1 This means that there are n N possible samples; the probability of drawing each of these is the same.
