Inlier

An inlier is a data value that lies in the interior of a statistical distribution and is in error. Because inliers are difficult to distinguish from good data values they are sometimes difficult to find and correct. A simple example of an inlier might be a value in a record reported in the wrong units, say degrees Fahrenheit instead of degrees Celsius.

Integrated Survey Processing

The concept that all parts of the survey process be integrated in a coherent manner, the results of one part of the process automatically giving information to the next part of the process. The Blaise system is an example of integrated software in which the specification of the Blaise Questionnaire gives rise to a data entry module as well as CATI and CAPI instruments. The goals of Integrated Survey Processing include the one-time specification of the data, which in turn would reduce duplication of effort and reduce the numbers of errors introduced into the system due to multiple specifications.

Interactive Data Review

Checking and correcting data in dialogue mode using video terminals. It can be applied during data entry or on data that are already in machine-readable form. The questionnaire is immediately reviewed after adjustments are made. The results are shown on a video terminal and the data editor is prompted to adjust the data or override the error flag. This process continues until the questionnaire is considered acceptable by the automated review process. Then results of the next questionnaire's review by the auto review processor are presented. A desirable feature of Interactive Data Editing Software is to only present questionnaires requiring adjustments.
