Frequently Asked Questions
An IQ (Intelligence Quotient) test measures various cognitive abilities such as logical reasoning, pattern recognition, spatial ability, working memory, and processing speed. IQ Lab evaluates these five domains to provide a balanced overview.
The standard average IQ score is 100 with a standard deviation of 15. Approximately 68% of the population scores between 85 and 115. A score of 130 or higher puts you in the top 2% of the population.
This test is constructed based on psychometric principles and designed to yield a solid estimation of your capabilities. However, it is not a clinical diagnosis tool. For a formal, clinically certified assessment, consulting a professional psychologist is recommended.
The Quick Test takes about 5 minutes (10 questions), and the Full Test takes about 25 minutes (50 questions). Each question has its own dedicated timer, and it automatically progresses if time runs out.
Your score is derived by a weighted average of your performance across the 5 domains, then normalized relative to global population distributions. The final score ranges between 70 and 130, accompanied by standard deviations and percentiles.
