Which of the following are characteristics of a good psychological test?

A good psychological test is characterized by being standardized, reliable, valid, and norm-referenced.

Standardization ensures that the test is administered and scored in a consistent manner across different populations; this uniformity allows for comparisons and interpretation of results. Reliability refers to the consistency of the test results over time or across different situations, which is crucial for determining if the test truly measures what it claims to measure. Validity examines whether the test accurately assesses the specific psychological construct it is intended to measure, ensuring that the outcomes are meaningful and applicable. Norm-referenced assessment allows for the interpretation of an individual's score in relation to a larger group, which provides context and understanding of where an individual stands in comparison to others.

In contrast, factors such as being entertaining, subjective, or variable (as mentioned in the first option) do not contribute to the scientific rigor or usefulness of the test. Attributes like being expensive, complex, and informal do not align with standard testing practices, which prioritize accessibility and clarity. While multiple choice questions and true/false sections can be part of a psychological test, they do not inherently define the quality or effectiveness of the test itself; the structural format alone does not ensure the essential characteristics of reliability, validity, and standardization.
