2. 1. Observed score equating with covariates

   Author : Kenny Bränberg; Marie Wiberg; Xavier de Luna; Dag Sörbom; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Equating; observed score equating; true scores; item response theory; linear equating function; equipercentile equating; kernel equating; covariates; linear regression; mean squared error; Statistics; Statistik; Statistics; statistik;

   Abstract : In test score equating the focus is on the problem of finding the relationship between the scales of different test forms. This can be done only if data are collected in such a way that the effect of differences in ability between groups taking different test forms can be separated from the effect of differences in test form difficulty.

5. 3. Contributions to Kernel Equating

   Author : Björn Andersson; Fan Yang-Wallentin; Marie Wiberg; Alina A. von Davier; Jorge González; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; observed-score test equating; item response theory; R; equipercentile equating; asymptotic standard errors; non-equivalent groups with anchor test design; Statistics; Statistik;

   Abstract : The statistical practice of equating is needed when scores on different versions of the same standardized test are to be compared. This thesis constitutes four contributions to the observed-score equating framework kernel equating. READ MORE

6. 4. Extensions of the kernel method of test score equating

   Author : Gabriel Wallin; Marie Wiberg; Jenny Häggström; Anton A. Béguin; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Test equating; Nonequivalent groups; Standard error of equating; bandwidth selection; log-linear models; item response theory; Statistics; statistik;

   Abstract : This thesis makes contributions within the area of test score equating and specifically kernel equating. The first paper of this thesis studies the estimation of the test score distributions needed in kernel equating. READ MORE

7. 5. Theory and validity evidence for a large-scale test for selection to higher education

   Author : Jonathan Wedman; Marie Wiberg; Per-Erik Lyrén; Jo-Anne Baird; Umeå universitet; []

   Abstract : Validity is a crucial part of all forms of measurement, and especially in instruments that are high-stakes to the test takers. The aim of this thesis was to examine theory and validity evidence for a recently revised large-scale instrument used for selection to higher education in Sweden, the Swedish Scholastic Assessment Test (SweSAT), as well as identify threats to its validity.
