1. What is IQ?

IQ (Intelligence Quotient) is a score derived from standardized tests designed to measure human intelligence. The traditional IQ formula compares a person's mental age to their chronological age.

2. How Does the Calculator Work?

The calculator uses the basic IQ equation:

Where:

• Mental Age — The age level of mental ability
• Chronological Age — The actual age in years

Explanation: If a 10-year-old child has the mental ability of a 12-year-old, their IQ would be 120 (100 × 12/10).

3. Importance of IQ Calculation

Details: While modern IQ tests use more sophisticated methods, this basic formula helps understand the concept of intelligence quotient and how it relates to age-appropriate cognitive abilities.

4. Using the Calculator

Tips: Enter mental age and chronological age in years. Both values must be positive numbers. The calculator will compute the IQ score.

5. Frequently Asked Questions (FAQ)

Q1: Is this the same as modern IQ tests?
A: Modern tests use more complex statistical methods, but this formula demonstrates the original concept of intelligence quotient.

Q2: What is considered an average IQ?
A: An IQ of 100 is considered average, as it represents mental age equal to chronological age.

Q3: Can IQ change over time?
A: Yes, IQ scores can change with education, environment, and other factors, though they tend to remain relatively stable.

Q4: What are the limitations of this simple formula?
A: It doesn't account for the full complexity of intelligence and is most accurate for children. Modern tests use standardized distributions.

Q5: How is mental age determined?
A: Originally through standardized tests comparing performance to age norms. Modern tests use more sophisticated methods.
