Practical Rasch Measurement - Further Topics

Practical Rasch Measurement - Further Topics

taught by Everett Smith

Aim of Course:

Continues the exploration of Rasch theory and its application in the Winsteps software begun in Practical Rasch Measurement-Core Topics. The visual step-by-step tutorial propels you along the road to success. This online course, "Practical Rasch Measurement - Further Topics" introduces exciting new topics and delves into earlier topics more deeply. Meaningful findings always require careful screening of data, and may require judicious data selection and editing. Even the most profound findings are ignored by decision-makers unless they are presented clearly, powerfully and briefly. In accord with these precepts, you are guided toward successfully analyzing data and communicating your findings.

This course may be taken individually (one-off) or as part of a certificate program.
