| Definition: |
|
The actual population value that would be obtained with perfect measuring instruments and without committing any error of any type, both in collecting the primary data and in carrying out mathematical operations.
|
| Context: |
An idealized concept of a quantity which is to be measured; in some cases it can be achieved, but in others there is disagreement as to the definition of the quantity. Illustrations are the number of persons who are "unemployed," and the dollar value of farm sales.
In most surveys an approximation to the "true" value is used, defined in such a way that one would expect to be able to measure it provided there were sufficient time, money, knowledge of techniques, etc., and no errors in the reporting, collection, and processing of the data.
