What Is an IQ Test and How Does It Work?

An Intelligence Quotient (IQ) test is a standardized assessment designed to measure a person’s cognitive abilities and intellectual potential. These tests evaluate various mental functions, including reasoning, problem-solving, memory, and comprehension. While best online IQ tests do not measure overall intelligence or creativity, they provide a useful benchmark for comparing intellectual abilities across different individuals. In this article, we will explore what an IQ test is, how it works, and its significance in various fields.

Understanding IQ Tests

2. Types of IQ Tests

Several standardized IQ tests are widely used, including:
