1. 1. A perfect score : Validity arguments for college admission tests

   Författare :Per-Erik Lyrén; Christina Stage; Marie Wiberg; Simon Wolming; Stephen G. Sireci; Umeå universitet; []
   Nyckelord :college admission tests; SweSAT; validity; interpretive arguments; predictive validity; equating; item revisions; subscores;

   Sammanfattning : College admission tests are of great importance for admissions systems in general and for candidates in particular. The SweSAT (Högskoleprovet in Swedish) has been used for college admission in Sweden for more than 30 years, and today it is alongside with the upper-secondary school GPA the most widely used instrument for selection of college applicants.

3. 2. A fair score? : group independent validity arguments for college admission tests

   Författare :Marcus Strömbäck Hjärne; Ewa Rolfsman; Christina Wikström; Per-Erik Lyrén; Jan-Eric Gustafsson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fairness; Validity; Immigration; Dyslexia; Special populations; SweSAT; didactics of educational measurement; beteendevetenskapliga mätningar;

   Sammanfattning : This thesis aims to investigate fair use of test scores for admission to higher education. In this thesis, fairness is narrowed down to an instrumental definition relating to a fair interpretation of test scores. The focus is on the use of the Swedish Scholastic Aptitude Test (SweSAT) for admission decisions. LÄS MER

4. 3. Observed score equating with covariates

   Författare :Kenny Bränberg; Marie Wiberg; Xavier de Luna; Dag Sörbom; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

   Sammanfattning : In linkage analysis or, in a wider sense, gene mapping one searches for disease loci along a genome. This is done by observing so called marker genotypes (alleles) and phenotypes (affecteds/unaffecteds) of a pedigree set, i.e. LÄS MER
