Measurement, Reliability and Scales Construction in a View of Classical True-Score Theory

摘要: The main objective of this article was to describe issues related theory measurement and discuss significant role selected reliability methods in a view Classical True-Score Theory - CTM. In consequence the emphasis put on description comparison between different assessment such as: test-rest, parallel-test, split-half or internal consistency. author investigated them primarily context psychometrics its general applications area marketing customers research studies. second part article, new perspective (Item Response IRT) discussed. Later on, both concepts CTM IRT were compared. Although researchers field have paid considerable attention theory, another (e.g. marketing) these topics somehow been neglected. And recent advances statistical analysis drawn increasing nagging problems measurement.
