What is ShinyItemAnalysis?
ShinyItemAnalysis is an R package and an interactive online application for the psychometric analysis of educational tests, psychological assessments, health-related and other types of multi-item measurements, or ratings from multiple raters.
It was developed with the aim to support teaching of psychometric concepts, present psychometric research and to empower routine psychometric analysis.
Wide range of methods
- Exploration of total and standard scores
- Validity and reliability
- Traditional item analysis
- Item analysis via logistic regression models and their extensions
- Item analysis via IRT models
- Detection of differential item functioning
ShinyItemAnalysis provides model equations, parameter estimates and their interpretation.
Selected R code
All methods include sample R code which is ready to copy and paste into R and run locally.
Several toy data sets are ready to use. You can also upload and analyze your own data.
ShinyItemAnalysis offers automatic generation of HTML and PDF reports.
ShinyItemAnalysis is a free software and you can redistribute it and or modify it under the terms of the GNU GPL 3.
