1. Meaning and basic concepts of psychometrics
With the advent of such a field of research as differential psychology,
psychometrics received its new development, since special rules and
requirements for the principles of measurement began to arise, following which
ensured its accuracy and reliability. In this regard, it became necessary to use a
concept that more accurately defines this area of measurement. It was supposed
to reflect not the entire set of psychological and psychophysiological
measurements, but only that which is related to differential psychological
characteristics. To use the term

around questions about what we measure, and what units of measurement we
have the right to use (what we measure). In addition, to the main problems,
which are solved by
Any test conclusions when using statistical test norms are relative. They depend
on the sample on which the test was standardized. The extent to which a
standardization sample allows the test to be applied to a wide population is
called the representativeness of the test norms. (Population - a category of
subjects of a certain social, professional or gender and age affiliation.) Test norm
- the average range of values on the scale
4) analysis of test problems, ensuring their reliability, validity and
representativeness.
Thus, knowledge of psychometrics allows a psychologist to competently
and correctly apply tests on a new population, to check the reliability and
representativeness of tests in new conditions. Strict adherence to psychometrics
helps to correctly apply foreign tests, and also allows you to develop new tests.
2. The accuracy of measuring instruments or the magnitude of the error.
The main directions of differential psychometrics are as follows.
1) the general theory of measuring psychological
phenomena, 2) designing methods based on it, 3)
psychometric adaptation of measuring instruments to new conditions
