Population see population of interest.
Identification information lists details such as the name and address of participants in a market research project whereby they can be identified. Implicit Alternatives are alternatives in a question that are not expressed openly. Such alternatives may have lower chance of being selected and therefore the data may be biased. Implicit Assumption is when all respondents are assumed to have the same level of knowledge on a subject. Implied Population is the population as suggested by the sample, ie it is that part of the population of interest that was available for the research.
