These data may have been collected from sources wealth the researcher’s firm or from sources outside the firm. The key point Is that the data were collected for some other project, or reason, than the current one.

A complete survey is called a “census. ” It involves contacting the entire roof you are interested in the total population or universe. The other category is more common; it is a sample survey. A sample is a representative part of a whole group (universe). Thus a sample survey involves examining only a portion of the total group in which one is interested, and from it, inferring information about the group as a whole. By sampling only a small portion of a large population,it is possible to collect data in far less time than would be required to survey the entire group.
The smaller amount of data gathered by sampling as opposed to surveying an entire population can mean large cost savings. Finally, a carefully selected sample may yield more accurate information than a less careful collection of data from the entire population. On the other hand, there are certain disadvantages of sampling. The main disadvantages stem from risk, lack of representatives of the sample, and insufficient sample size, each of which can cause errors. Inattention to any of these potential flaws will invalidate the survey results.
Surveys can also be classified by their method of data collection. Mail, telephone interview, and in-person interview surveys are the most common.
