Introduction To Measurement Theory,Used
Delivery time: 8-12 business days (International)
Introduction To Measurement Theory Bridges The Gap Between Texts That Offer A Mathematically Rigorous Treatment Of The Statistical Properties Of Measurement And Ones That Discuss The Topic In A Basic, 'Cookbook' Fashion. Without Overwhelming Novices Or Boring The More Mathematically Sophisticated, The Authors Effectively Cover The Construction Of Psychological Tests And The Interpretation Of Test Scores And Scales; Critically Examine Classical Truescore Theory; And Explain Theoretical Assumptions And Modern Measurement Models, Controversies, And Developments. Practical Applications, Examples, And Study Questions Facilitate A Better Understanding Of The Uses And Limitations Of Common Measures Of Test Reliability And Validity And How To Perform The Basic Item Analysis Necessary For Test Construction.
