The normal curve is split. A text box on the left side indicates that half the individuals with IQs from seventy to fifty five were achieving above the predicted or expected level based on IQ score. A text box on the right side indicates that half the individuals with IQs from seventy to fifty five were achieving below the predicted or expected level based on IQ score.
