1. What is IQ?

IQ (Intelligence Quotient) is a score derived from standardized tests designed to measure human intelligence. The modern IQ score is normalized with a mean of 100 and standard deviation of 15.

2. How Does the Calculator Work?

The calculator uses the IQ normalization formula:

Where:

• Test Score — Raw score from the test
• Mean — Average score of the population
• Standard Deviation — Measure of score variability
• 15 — Standard deviation for IQ scale
• 100 — Mean IQ score

Explanation: The formula converts a raw test score to a normalized IQ score based on the test's distribution parameters.

3. Importance of IQ Calculation

Details: IQ scores provide a standardized way to compare cognitive abilities across individuals, though they should be interpreted with caution as they don't capture all aspects of intelligence.

4. Using the Calculator

Tips: Enter your raw test score, the test's mean score, and standard deviation. Common values are mean=100, SD=15 for many standardized tests.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a normal IQ?
A: Most people (68%) score between 85 and 115. Scores above 130 are considered very superior, while below 70 may indicate intellectual disability.

Q2: Can IQ change over time?
A: Yes, IQ scores can change due to education, environment, and other factors, though they tend to be relatively stable in adulthood.

Q3: Are all IQ tests the same?
A: No, different tests may measure different aspects of intelligence and have varying means and standard deviations.

Q4: What are the limitations of IQ tests?
A: They don't measure creativity, emotional intelligence, or practical skills, and can be affected by cultural bias.

Q5: How accurate is this calculator?
A: It provides a general estimate but for official results, use the conversion tables provided with your specific test.
