The District Engineer U. S. Army Engineer District, Seattle 1519 Alaskan Way South Seattle, Washington 98134 This letter is a report of work performed under contract #NPSSU-67-401. I have completed the specified scope of work under that contract as follows: (a) I have designed three questionnaires to obtain data needed for economic analysis. One of these is for the Intra-Coastal Waterway Study, another for the Puget Sound and Adjacent Waters Study, and the third is a modification of the second pertaining only to trailer boats. The first in questionnaires have been mailed out and tabuluted, and the third has been mailed but is awaiting tabulation by your offices. (b) I have specified the number of questionnaires (c) This letter is the required written report. The preparation of the questionnaires specified in the contract proceeded in a very careful and systematic way. Several conferences defined the problems which the surveys were intended to investigate and resulted in an initial draft for each questionnaire. The initial draft was circulated to interested parties, and, on the basis of their comments and of additional conferences with Corps of Engineers personnel and others, there was some redefinition of the problems and revision of the questionnaires. Each questionnaire was then field tested. The test was conducted by Corps personnel and consisted of observed completion of the questionnaire by approximately twenty arbitrarily selected members of the boating population. A final revision of the questionnaire was made as a result of the test. Whenever we make inferences about a population by investigating a portion of that population rather than the entire population, we run the risk that those inferences will be in error. But, whenever we select our sample randomly, we are helped by the fact that it is then subject to the laws of probability, and we can make some statement about the probability of our error. That statement depends upon the variability of the answers which we receive to the questions we ask, and upon the size of our sample. If all respondents give the same or very similar answers, then our error will be smaller. If all respondents give widely differing answers, then our error will be larger. If the sample is a very large one, then our error will be smaller. If the sample is a very small one, then our error will be larger. Since we do not know before we draw our sample how variable the answers to our questions will be, we estimate or assume the extent of that variability and then design our sample size to give us some probability of error and some limit of error that we are willing to accept. Thus, in these surveys, the estimates of variability of response and of the numbers of people who would respond to the questionnaire, coupled with the acceptable limits and size of error, led to the decision to draw a sample of 1600 for each survey. Therefore, for each questionnaire, Corps personnel drew a random sample of 1600 boat owners from the United States Coast Guard list of registered boats in the geographic area under consideration. The questionnaires were then mailed to this sample with an explanatory letter and a request to respond, and after ten days, the members of the sample who had not responded were sent another copy of the questionnaire with an additional request to respond. After adjustment for minor errors in the Coast Guard list, which were discovered during the mailing, approximately 70 per cent of each sample responded. This is an unusually high response rate for mail samples of this sort and is a result of which the Corps can be justly proud. Each questionnaire was then edited for errors and consistency by Corps personnel and coded for computer tabulation. In addition, Corps personnel wrote the computer program to my specifications, and I personally reviewed the results of the test runs of that program. After the completion of computer tabulation, I held a conference with Corps personnel regarding the interpretation of the results. In addition, I stand ready to review their final report should they wish to have me do so. Strictly speaking statistical reliability for surveys such as these cannot be computed for the entire population of boat owners, because 30% of the sample did not respond. However, for that sub-population represented by the 70% who did respond, we can make very precise estimates of our error. These are still estimates, however, because in order to know the true amount of error, we would have to know the exact values of the population parameters and these, of course, we could never know unless we had investigated the entire population, rather than just a sample. |
