Learning Outcomes

At the conclusion of this course students will be able to import data from SPSS, SAS, Stata and Excel, install and operate Winsteps software, and analyze dichotomous and polytomous data. They will investigate test functioning and test equating with a goal of successfully analyzing data and communicating their findings to decision makers.

  • Deal with missing data
  • Calculate correlations and local fit-statistics
  • Estimate polytomous models
  • Deal with differential item functioning
  • Perform test equating
