© 2007 Prentice Hall11-7Define the Target PopulationThe target population is the collection of elements orobjects that possess the information sought by theresearcher and about which inferences are to be made.The target population should be defined in terms ofelements, sampling units, extent, and time.Anelementis the object about which or from whichthe information is desired, e.g., the respondent.Asampling unitis an element, or a unit containingthe element, that is available for selection at somestage of the sampling process.Extentrefers to the geographical boundaries.Timeis the time period under consideration.
