Document Summary
The target population is the population we want to make inferences about, while the sampled population is the population from which the sample is actually selected. It is important to understand that these two populations are not always the same. In the dmi example, the target population consists of all people who purchased a dmi per- sonal computer. The sampled population, however, might be all owners who sent warranty registration cards back to dmi. Not every person who buys a dmi personal computer sends in the warranty card, so the sampled population would differ from the target population. In sample surveys it is necessary to distinguish between the target population and the sampled population. Conclusions drawn from a sample survey apply only to the sampled population. Whether these conclusions can be extended to the target population depends on the judg- ment of the analyst.
