What is the psychometric domain of psychology?
Psychometrics refers to the design and interpretation of tests that measure psychological values such as aptitude, ability, personality, memory, happiness and intelligence. The Myers-Briggs or Big Five Personality tests would be an example of this domain.
Understanding the terms Validity and Reliability are key in this domain. Psychology is especially challenged to demonstrate validity because our research is into somewhat less tangible variables (“happiness”, “intelligence”, “stress”). Make sure you understand what validity and reliability are in reference to creating and interpreting psychological tests.
It is the domain of psychology dealing with quantifiable measures. It covers taking data and calculating various statistics to both explain that data and makes inferences. It also focuses on the creation and implementation of various forms of testing—personality tests, questionnaires, etc.
