What is IQ and What Does an IQ Test Measure?

IQ, or Intelligence Quotient, is a score that reflects a person’s cognitive abilities compared to the general population. It is commonly used to understand how efficiently someone can process information, solve problems, think logically, and learn new skills.

An IQ test evaluates several areas of intelligence, including:

Logical and analytical reasoning
Problem-solving ability
Memory and pattern recognition
Processing speed and attention

While IQ tests do not measure creativity or emotional intelligence, they provide a useful benchmark for understanding cognitive strengths and areas for improvement.

How Is Your IQ Score Calculated?

Your IQ score represents how your performance compares to the general population based on statistical analysis and cognitive testing.

Test Performance

You complete a series of logic, reasoning, pattern recognition, memory, and problem-solving questions. Your raw score is recorded.

Statistical Comparison

Your score is compared to large-scale population data using a statistical method called standard deviation.

Final IQ Score

The average IQ is set to 100. Your final score shows whether you are below, average, or above the population mean.

Most IQ tests use the formula:
IQ = 100 + (Your Score – Average Score) / Standard Deviation × 15
