Document Summary

Objective: to select n people out of n with each n having an equal chance of being selected. Procedure: table of random numbers or computer generated random numbers n = 1,000 (n/n 4. 5%) Objective: to select n people out of n with each n having an equal chance of being selected within each stratum. Procedure: divide population into subgroups (strata) n1, n2, n3 ni. Then do simple random sample of n/n in each strata. Objective: stratum = married with & without children. N = 22,000 n = 1,000 randomly select households n1 = 1,000 x 55% = 550 n2 = 1,000 x 45% = 450. N = 22,000 n = 1,000 randomly selected households n1 = 1,000 x 50% = 500 n2 = 1,000 x 50% = 500. Objective: systematically select n people out of n such that n is a random sample of n. Randomly select a number between 1 and k.
