  1. 1. Observed score equating with covariates

    Detta är en avhandling från Umeå : Department of Statistics, Umeå university

    Författare :Kenny Bränberg; Umeå universitet.; [2010]
    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; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap 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.

  2. 2. Contributions to Kernel Equating

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Björn Andersson; Uppsala universitet.; [2014]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Extensions of the kernel method of test score equating

    Detta är en avhandling från Umeå : Umeå universitet

  5. 5. A perfect score Validity arguments for college admission tests

    Detta är en avhandling från Umeå : Institutionen för Beteendevetenskapliga mätningar, Umeå Universitet

    Författare :Per-Erik Lyrén; Umeå universitet.; [2009]
    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.
