IRT Analyses Using the Statistical Software R
This workshop will provide an introduction into the use of R, the R programming environment RStudio,and the TAM package, a powerful function package within R to conduct item response theory (IRT) analyses. Using these tools, we will go through all steps necessary to do an IRT analysis, and you will directly apply them either on language test data provided to all participants or on your own data set that you bring to the workshop.
