T 1.1 Difference between a sample and a population
* Population is the area in which you are trying to get information from. * This meaning of population is also used in survey research, but this is only one of many possible definitions of population. * Examples: Cedar Crest students; trees in North America; automobiles with four wheels; people who consume olive oil.
| * Sample is a section of your population that you are actually going to survey.
