Definition:

The quality of data is measured according to its reliability and validity; the completeness and accuracy of a data set. It is usually measured by comparing the data set to another data set identified as the "gold standard", and assessing the level of agreement. For example, linking with a data source such as census data, vital statistics, or surveys to determine missing information.
