AG EXT 606 TECHNIQUES OF MEASUREMENT IN BEHAVIOURAL SCIENCES                                                           (3L+1P) III

Objective
  The course aims at development of conceptual understanding of psychometrics and its application in constructions of scales for measuring psychological characteristics/traits. The learners will be exposed to various methods of scale construction, scalogram analysis and testing the reliability and validity of scales. It is also intended to orient the learners towards other psychometric methods like Q-sort, semantic differential and rating scales besides multivariate techniques.
