>>508668059 (OP)Le Serb concerning himself about IQ
The average for the total sample of 608 is 48 items correct, which is at the 31st percentile with an IQ equivalent of 93. If an adjustment is
made for the increase in American norms of two IQ points a decade (Lynn, 2006, p. 5) from the standardization of 1993 to the approximate date of the Serbian study (2007 = 14 years), the Serbian IQ is reduced to 90. If a further reduction is made of two IQ points because the American IQ is 98 due to the inclusion of African Americans with a mean IQ of 85 (Lynn, 2006, p. 5), the final best
estimate of the Serbian IQ is 88. There were no sex or religious differences (males = 90, females = 90; Muslims = 91, Christians = 89;
Fs < 1.00, ns).
