Samples, Sampling and Sample Collection
In disease investigation, the term sample is used in two different ways; as a synonym for specimen, as in blood sample, and in the statistical sense of a sub-collection or sub-set of units drawn from the population. Collection and analysis of samples is the basis of investigation, and the validity of the results and conclusions of any study is totally dependent on the quality of the samples collected. Samples of the specimen and statistical types will be discussed separately later in this chapter; a few general principles will be considered first.
