Outlier detection tool

摘要

A test results screening tool allows capture of test item and test results data and provides a reviewer with a robust set of tools for entering screening criteria and display of test results by both test subject and test center. The tool includes parametrically sets flags for unwanted testing behaviors including test item harvesting, test subjects with pre-knowledge of the test subject matter, and proxy test takers for some a portion of a test.

主权项

1. A computer having computer executable instructions stored in a non-transitory computer storage media that, when executed on a processor of the computer, implement a tool for use in analysis of test results, the tool comprising:
a screening criteria entry module implementing a screening criteria entry area for (i) entry of a plurality of screening criteria indicating results to be flagged as behavior inconsistent with legitimate test taking, and (ii) plotting a composite result for at least one screening criteria of the plurality of screening criteria as a visual indicator of possible screening criteria set points; an input area module implementing an input area for entry of test results for a test; a calculation engine module implementing a calculation engine that develops statistical analyses of the test results; an initial results screening module implementing an initial results screening area showing the statistical analysis by test subject, including display of test results meeting the plurality of screening criteria; a test record summary module implementing a test record summary area displaying test subject results by test item, including (i) flagged test results data meeting the plurality of screening criteria, and (ii) a final status determination of a reviewer, wherein a final status determination of a behavior inconsistent with legitimate test taking causes the corresponding test subject to fail the test; a test record detail module implementing a test record detail area comprising an indication of test subjects meeting a test pre-knowledge screening criteria of the plurality of screening criteria; and a proxy screening module implementing a proxy screening area comprising an indication of test subjects meeting a test proxy screening criteria of the plurality of screening criteria.
