Reading Comprehension Tests for Children: Test Equating and Specific Age-Interval Reports [PDF]

Frontiers in Psychology, 2021
Equating is used to directly compare alternate forms of tests. We describe the equating of two alternative forms of a reading comprehension test for Brazilian children (2nd to 5th grade), Form A (n = 427) and Form B (n = 321).

Bias-Reduced Haebara and Stocking–Lord Linking

J
Haebara and Stocking–Lord linking methods are frequently used to compare the distributions of two groups. Previous research has demonstrated that Haebara and Stocking–Lord linking can produce bias in estimated standard deviations and, to a smaller extent,

Implementation Aspects in Simulation Extrapolation-Based Stocking–Lord Linking

Applied Sciences
Stocking–Lord (SL) linking is commonly used for group comparisons based on dichotomous item responses. Recently, the simulation extrapolation (SIMEX) method for SL linking has been introduced within the two-parameter logistic (2PL) model to reduce the ...

SIMEX-Based and Analytical Bias Corrections in Stocking–Lord Linking

Analytics
Stocking–Lord (SL) linking is a popular linking method for group comparisons based on dichotomous item responses. This article proposes a bias correction technique based on the simulation extrapolation (SIMEX) method for SL linking in the 2PL model in ...

Linking Error Estimation in Stocking–Lord Linking

Foundations
Stocking–Lord (SL) linking is a widely used linking method based on item response theory (IRT). This article examines the variability in SL linking parameter estimates within the two-parameter logistic (2PL) model.

The Impact of Latent Density Misspecification on Item Response Theory Equating Methods [PDF]

Appl Psychol Meas
Item response theory (IRT) observed and true score equating are often conducted assuming that the latent variable is normally distributed. Although this might be a reasonable assumption for many educational and psychological assessments, not all ...

SNSequate: Standard and Nonstandard Statistical Models and Methods for Test Equating

Journal of Statistical Software, 2014
Equating is a family of statistical models and methods that are used to adjust scores on two or more versions of a test, so that the scores from different tests may be used interchangeably.
