- Title
A Reply to Loerke, Jones, and Chow (1999) on the "Psychometric Benefits" of Linked Items.
- Authors
Pope, Gregory A.; Harley, Dwight D.
- Abstract
The Loerke, Jones, and Chow (1999) article entitled “Psychometric benefits of soft-linked scoring algorithms in achievement testing” contains many methodological and psychometric errors. Some of these include: a) ignoring basic assumptions of classical test theory and item response theory, b) incorrectly using and interpreting item and test statistics such as point-biserial correlation coefficients and KR-20 reliability coefficients. It is essential that education professionals are made aware of these problems and appreciate that the findings of the study cannot be used as “evidence” that linked items have psychometric benefits.
