Random Notes on Randomness: A Survey Concern.
Achilles, C. M.; Lintz, M. N.
Researchers conducted surveys of public attitudes in two Tennessee school systems in 1984-85 and 1985-86. Although interested in the survey results, one purpose of the researchers was to determine some inexpensive and relatively simple survey procedures. The researchers sought--through several pilot studies--to identify an efficient, parsimonious and effective sampling procedure. The final random-sample plan used the fact that most city polling places are in public schools. A history of the number of people registered and voting at each polling place was obtained from the election commission. The percentage needed at each polling place to establish a sample of confidence (.95) was calculated. Trained volunteers distributed surveys at polling places and encouraged respondents to complete the survey. Return rate was high (over 90 percent). People (other than the random group) who insisted on completing the survey were allowed to do so. By keeping the completed instruments separate, there were two sets of surveys: the random and non-random samples. Results from comparisons of: (1) random with non-random samples; and (2) random sample results with the pilot studies in both communities are extremely similar. In fact, a convenience sample (n=82) in one system provided essentially the same results as the nearly 5,000 responses to the full-scale, mail-out survey. The survey instruments and summary results are appended. (Author/LMO)
