Detailed explanation-1: -A graph of intelligence quotient (IQ), a measure of human intelligence, is an example of normal distribution, in which the most frequent scores are clustered near the center. The mean score is 100. The shaded region between 85 and 115 accounts for about 68 percent of the total area, hence 68 percent of all IQ scores.
Detailed explanation-2: -IQ scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15.
Detailed explanation-3: -IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. About 68% of individuals have IQ scores in the interval 100 ± 1 ( 15 ) = [ 85, 115 ] . About 95% of individuals have IQ scores in the interval 100 ± 2 ( 15 ) = [ 70, 130 ] .
