DESCRIPTION:In psychometrics\, concepts such as nominal\, ordinal and inte
 rval scaling\, mean\, medium\, mode\, histogram\, cumulative histogram\, s
 tandard deviation and normal distribution\, not only need to be fully unde
 rstood but also applied in real world settings. They form the fundamental 
 building blocks for concepts such as error of measurement\, accuracy of es
 timation\, treatment effectiveness\, and the relationship between a score 
 and what it purports to measure. The classical psychometric parameters tha
 t assess reliability\, validity\, standardisation and equivalence continue
  to play a crucial role in the development and understanding of assessment
 . At the end of this session you should know how to assess the reliability
  and validity of an assessment\, and the impact on these assessments of co
 mplications such as range restriction and attenuation.
