one of the best lectures on psychometrics in the history of psychometrics. Thank you Doc. Combrinck

I use conquest but I have with the commands for run analysis for each dimension. because I want to measure dimensionality. any advice?

[@sellomoyo4628]

very informative

Hi Dr Combrinck, great presentation. One question, can rasch analysis be used to transform existing measures from ordinal to interval ? Or is it just used to validate those ordinal measures

It’s possible… see Oleg DSS 20 on good scholar

Your statement about Ordinal scales and Interval scale is questionable, R U sure?
