  2. 1. Motivational aspects of test-taking : measuring test-taking motivation in Swedish national test contexts

    Author : Eva Knekta; Hanna Eklöf; Anna Sundström; Rolf Vegar Olsen; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Test-taking motivation; Swedish national tests; validity; expectancy-value theory; task value; expectancies; young adolescents; self-report instrument; interview; structural equation modelling; test stakes; didactics of educational measurement; beteendevetenskapliga mätningar;

    Abstract : The overall aim of the work underlying this thesis was to improve the understanding of students’ test-taking motivation in connection to achievement tests for young adolescents. The thesis includes four studies and a summary. All four studies explore test-taking motivation and are all connected to validity in one way of another. READ MORE

  4. 2. Methods for interval-censored data and testing for stochastic dominance

    Author : Angel G. Angelov; Magnus Ekström; Maria Karlsson; Bengt Kriström; Per Johansson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interval-censored data; Informative censoring; Self-selected intervals; Questionnaire-based studies; Maximum likelihood; Permutation test; Two-sample test; Stochastic dominance; Four-decision test; Statistics; statistik;

    Abstract : This thesis includes four papers: the first three of them are concerned with methods for interval-censored data, while the forth paper is devoted to testing for stochastic dominance.In many studies, the variable of interest is observed to lie within an interval instead of being observed exactly, i.e. READ MORE

  5. 3. Contributions to generalized Wilcoxon rank tests

    Author : Marie-Louise Öhman; Hans Nyquist; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Censored data rank sum tests; Gehan s test; Generalized Wilcoxon test; Jackknifing; Two sample problem; Simulation; Survival data; Variance estimation; Influence function; Gross error sensitivity; Sensitivity curve; Misclassification; Statistics; computer and systems science; Statistik; data- och systemvetenskap; Statistics; statistik;

    Abstract : In unbalanced small sample size problems with right censorings, the variance estmators of linear rank statistics, may be biased. This is the case with the commonly applied variance estimators for the generalized Wilcoxon rank test statistics of Gehan and Prentice. READ MORE

  6. 4. Motivational beliefs in the TIMSS 2003 context : Theory, measurement and relation to test performance

    Author : Hanna Eklöf; Widar Henriksson; Simon Wolming; Svein Lie; Umeå universitet; []
    Keywords : test-taking motivation; TIMSS 2003; validity; construct validation; measurement; expectancy-value theory; self-concept; task value; factor analysis; eighth-grade students; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : The main objective of this thesis was to explore issues related to student achievement motivation in the Swedish TIMSS 2003 (Trend in International Mathematics and Science Study) context. The thesis comprises of five empirical papers and a summary. READ MORE

  7. 5. 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
