Considerable effort goes into the production of such a table, although one’s first thought might be that all that would be necessary would be to sit down and write down digits as they entered one’s head. A trial of this method shows quickly that such a list cannot be called random: A person invariably has particular tendencies; he or she may write down many odd digits or repeat certain sequences too often. To illustrate the use of such a table of random digits, a sample of size 5 will be drawn from the population of 98 blood cholesterols.
If the target population consists of all possible patients suffering from a certain illness and given a certain treatment, then no matter how many patients are studied, they must still be considered to be a sample from a very much larger population. DEFINITIONS OF TYPES OF SAMPLES 15 When it is feasible to study an entire population, one may learn more about the population by making a careful study of a small sample than by taking limited measurements on the entire population. In the example of the population of 4000 undergraduates, the epidemiologist could afford the time and effort necessary to carefully collect smoking histories and obtain information on type and amount of exercise that 400 undergraduates do but not on all 4000 undergraduates.
27 28 COLLECTING AND ENTERING DATA to be made on a variety of topics, such as who will be eligible for the study, what information is needed, and how the needed data will be obtained and analyzed (see van Belle et al. ). If the data have already been obtained and are in some type of computer records, it may be sensible first to transfer them to EXCEL files, since most statistical programs will accept EXCEL files. Different types of medical or public health studies tend to use mainly different types of data.
