Programming in R

En este taller introductorio vamos a acercarnos a la **Teoría de Respuesta al Ítem (TRI)** de una manera práctica y accesible. La TRI sirve para entender mejor **cómo funcionan los ítems (preguntas) de un test y cómo miden una habilidad o rasgo**. Nos permite ver, por ejemplo, si un ítem es más fácil o más difícil, si discrimina bien entre personas con distinto nivel, y si funciona de manera consistente. También es una herramienta muy útil para seleccionar los mejores ítems, acortar tests sin perder calidad y diseñar escalas más precisas. A lo largo del encuentro, vas a: \- Construir una comprensión conceptual de sus ideas principales\. \- Aplicar este método usando R\. \- Aprender a interpretar sus resultados para entender mejor cómo funcionan los ítems y qué aportan a la medición\. Este taller es **introductorio** y está dirigido a personas con un **conocimiento básico de escalas psicométricas**. **No requiere conocimiento previo de Teoría de Respuesta al Ítem.** **Requerimientos:** * R: 4.5.1 (mínimo) * RStudio: 2025.05.1 (mínimo, descargar [aquí](https://posit.co/downloads/)) * Instalar los paquetes **tidyverse, mirt y ltm**
