ABSTRACT

As indicated in the previous topic, a simple random sample is one in which every member of a population is given an equal chance of being included in a sample.

Putting names on slips of paper and drawing them from a hat is one way to obtain a random sample. Another way is to use a table of random numbers, a portion of which is reproduced in Table 1 near the end of this book. It consists of numbers that are unrelated to each other or to anything else. To use such a table, a researcher must give each member of a population a number name, and each name must contain the same number of digits. For instance, if there are 70 members of a population, the researcher should name one of the individuals 00 (it does not matter who the first individual is because the researcher is only renaming individuals with number names at this point-not selecting individuals). The researcher should name a second individual 01, name a third individual 02, and so on.1
