Detailed explanation-1: -An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance, one standard deviation below the median, and so on. Deviation IQs are now used for standard scoring of all IQ tests in large part because they allow a consistent definition of IQ for both children and adults.
Detailed explanation-2: -70 to 84: Borderline mental disability. 85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted.
Detailed explanation-3: -Only 15% of the population have an IQ level of 115 or above. An IQ above 115 is considered to be a ‘High IQ’ – beyond an ‘above average IQ’.
Detailed explanation-4: -The mean () IQ score for the entire population is 100. The standard deviation () is 15 points. If you have an IQ score of 115 (100 + 15), then you are 1 standard deviation above the mean (z = +1). If you have an IQ score of 85 (100 – 15), then you are 1 standard deviation below the mean (z =-1).
