Rasch Measurement - Further Topics - Statistics.com: Data Science, Analytics & Statistics Courses (original) (raw)

Overview

This course builds on previous knowledge of Rasch theory and the Winsteps software program. It focuses on teaching students to not only analyze data, but present it in a clear and powerful way. Students will learn how to screen data and make judicious data selection and editing decisions. Previous experience using Winsteps and Excel is recommended.

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.

Who Should Take This Course

Survey researchers, social scientists who use surveys or questionnaires in their work, education assessment analysts and managers.
