Assumptions (for now) Observation unit = sampling unit. Target population = sampling universe = sampling frame. N = finite number of OUs in the population. U = {1, 2, \u2026, N} is the index set for the OUs in the population. Sample. n = sample size (n is less than or equal to N ) S = index set for n elements selected from population of N units (S is a subset of U) It\u2019s not enough to assume EL = OU = SU. Straighten out universe vs. pop, el vs. SU.
