Correct answers produce a raw score, which can be compared with a reference average and spread. Estimated IQ = 100 + 15 × (raw score - reference mean) / reference standard deviation.
Suppose you score 18, while the reference mean is 15 with a standard deviation of 3. The estimate is 100 + 15 × (18 - 15) / 3 = 115.
