What is an IQ Test?

An Intelligence Quotient (IQ) test is a standardized assessment designed to measure human intelligence and cognitive abilities. IQ tests evaluate various mental skills including logical reasoning, pattern recognition, mathematical ability, and verbal comprehension.

The concept of IQ was first introduced by French psychologist Alfred Binet in the early 1900s. Today, IQ tests are widely used in educational, clinical, and research settings to assess cognitive functioning.
