The last stage of the Current Population Survey chooses addresses within small areas called blocks. The method used is systematic random sampling. An example will illustrate the idea of a systematic sample. Suppose that we must choose 4 addresses out of 100. Because 100/4=25, we can think of the list as four lists of 25 addresses. Choose 1 of the first 25 at random. The sample will contain this address and the addresses 25, 50, and 75 places down from it. If 13 is chosen, for example, then the systematic random sample consists of the addresses numbered 13, 38, 63, and 88. 1. Use this random digits table to choose a systematic random sample of 5 addresses out of 200. Enter the table at line 120
The addresses numbered are selected (list the numbers in increasing order).
2. The systematic random sample above gives all individuals the same chance to be chosen.
True False
3. A systematic random sample is a simple random sample.
