This is a graph showing the average distribution of IQ scores. The X axis is labelled 'IQ score' and the Y axis is labelled 'numbers of individuals'. The graph then shows a symmetrical bell curve, showing low numbers of individuals for IQ scores below 70. The section below 70 IQ is shaded in and labelled '2.5% with intellectual disability'. The curve then rises up to the peak, reaching the mean IQ value of 100. This middle segment is labelled as containing 95% of the population. Then the curve gradually descends back down as IQ score increases. The area beyond IQ 130 is shaded and labelled '2.5% exceptionally able'.
