Sample Size Planning in Item Response Theory: A Tutorial

2024-07-24

Abstract excerpt

<p>Although item response theory (IRT) models offer well-established psychometric advantages over traditional scoring methods, they remain underutilized in practice. Following a brief introduction to the IRT framework, we emphasize its major advantages and explore potential applications in various research areas. The main part of this tutorial provides a comprehensive, step-by-step guide to Monte Carlo simulation-...
