11) Which of the following sample plans would NOT be considered a probability sample? A) simple random sample B) systematic sample C) cluster sample D) judgment sample E) stratified sample 12) Using a table of random numbers to draw a simple random sample requires that every member of the ________ be uniquely identified (i.e., numbered). A) population B) sample C) numbers D) Table E) sample unit 13) Which of the following statements would NOT apply to the accuracy of a sample? A) accuracy is defined as the amount of sample error due to the size of the sample B) sample findings can be generalized to the population with a +x% approximation C) as sample size increases, sample error decreases D) large gains in accuracy occur all the way to a sample size of 10,000 E) “e” represents the desired accuracy for a sample 14) Calculation of the “skip interval” is important in which sampling plan? A) simple random sample B) systematic sample C) “skip” sample D) cluster sample E) interval sample 15) Which of the following is NOT a practical constraint that may force sample size adjustments? A) time pressure B) study objective C) cost constraint D) data analysis procedures E) skills of the researcher 16) In practice, simple random sampling should be strongly considered: A) if the population is small and can be numbered easily. B) in telephone surveys where random digit dialing programs cannot be used to generate numbers. C) when population units are stored in an electronic file allowing computer programs to run quota samples. D) when a complex random sample proves too difficult for the researcher. E) for underdeveloped countries only. 17) Which of the following may be used to overcome the problems of unlisted numbers, “Do Not Call” lists, and population members without land lines? A) systematic sampling B) plus-one random digit dialing C) CATI systems D) random digit dialing E) an online phone directory 18) Simple random sampling is NOT a wise choice when you have: A) a large population. B) a small population. C) a sample frame in electronic format. D) a large population that is not in electronic format. E) a small population that is not in electronic format. 19) One of the advantages of systematic sampling is that: A) it is more representative in the final analysis. B) the listing of the population may contain hidden periodicities. C) it is not necessary to obtain a hard-copy listing. D) it has “economic efficiency;” it is less time consuming and easier to select. E) it has very little problem with sample frame error. 20) A sampling method that separates the population into subgroups where each subgroup represents the entire population is called: A) cluster sampling. B) subgroup sampling. C) stratified sampling. D) systematic sampling. E) sub-sampling.
