Levitt comes up with a equation which relates ELO and IQ score: ELO ~ (10 x IQ) + 1000Intelligence test scores typically follow what is known as a normal distribution, or a bell-shaped curve in which most scores lie near or around the average IQ test score. For example, the majority of scores (about 68%) on the Wechsler IQ tests tend to lie between plus 15 or minus 15 points from the average score of 100. Thus, if a child of age 10 had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/ 10 × 100, or 120.
