Abstract: Starting from the „rough” use of 1,500-1,800 subject samples in field researches with populations of the dimensions of a medium town, a capital or an entire country, which generates doubts and possible questions related to the representativeness of the investigated samples as well as to the conclusions of these researches, we developed the reconstruction of the necessary interactions in determining the sample volume, and also identified some inadvertencies. Some improvements solutions were also recommended.

Keywords: confidence interval; distribution laws; probable error; representativeness; sample volume. (search for similar items in EconPapers)
