The correct formula for determining IQ according to William Stern is (MA/CA) × 100. This formula uses an individual's mental age (MA) and their chronological age (CA) to determine their IQ score. MA is calculated based on performance on tasks typically characterized as measures of intelligence that are appropriate for a specific age group, whereas CA is the individual's actual age. By dividing the MA by the CA and multiplying by 100, an individual's IQ score is determined.
