Intelligence tests are assessment tools designed to measure an individual's cognitive abilities, including problem-solving skills, logical reasoning, and verbal comprehension. These tests provide a numerical score that represents the person's intelligence level relative to their peers.
Standardization refers to the process of developing uniform procedures for administering and scoring intelligence tests so that they can be compared across individuals or groups.
Validity is the extent to which an intelligence test accurately measures what it is supposed to measure. It ensures that the test accurately reflects an individual's intellectual abilities.
Reliability refers to the consistency of scores obtained from an intelligence test. A reliable test produces consistent results when administered multiple times or by different examiners.
