Which of the following is NOT a feature of simple random sampling?

Simple random sampling is a fundamental method used in statistics that ensures each member of a population has an equal and known chance of being selected. An essential characteristic of this sampling method is that the selection process is completely random, typically implemented through random number generators or similar techniques.

The requirement for each member to have equal chances means that all individuals in the population should be equally likely to be chosen. This eliminates bias in the selection process, which is not the case when selection is based on convenience. Convenience sampling, on the other hand, involves selecting individuals who are easily accessible, which does not adhere to the principles of simple random sampling.

Additionally, to conduct simple random sampling effectively, a complete list of the population is necessary. This complete list ensures that every potential participant has a chance to be included in the sample. Therefore, maintaining randomization through generations or other methods and having access to a complete population list are key features of simple random sampling.
