 (BVD) [none found]  (POD) ”A Simple Random Sample is a sample chosen using a method that ensures that each different possible sample of the desired size has an equal chance of being the one chosen.” p. 34  (RC) “....gives each member of the population the same chance of being selected for the sample. Moreover, your selection method should ensure that every possible sample (of the desired sample size) has an equal chance of being the sample ultimately selected.” p 57  (YMS) “A simple random sample of size n consists of n individuals from the populations chosen in such a way that every set of n individuals has an equal chance to be the sample actually selected.” p 335  (WSC) “In simple random sampling, all possible samples of a given fixed size are equally likely. All units have the same chance of belonging to the sample, all possible pairs of units have the same chance of belonging to the sample, all possible triples of units have the same chance, and so on..” p. 231
