Quizplus · Accepted Answer

Standardization of a psychological test refers to the use of uniform procedures in the administration and scoring of a test. This ensures that the scores obtained from the test have a consistent meaning and can be compared to scores obtained by others who have taken the same test. Standardization also involves the use of a representative sample during test development, which helps ensure that the test is reliable and valid for use with a wider population.
