Explanation: David Wechsler could be credited with the design of the most widely used individual intelligence test, The Wechsler Adult Intelligence Scale. The Wechsler Adult Intelligence Scale outputs scores for verbal comprehension, perceptual organization, working memory, and processing speed in addition to the overall performance score. Scores obtained are often standardized ( mean of 0 and standard deviation of 1). The intelligence score could be derived from the standardized score of the normal curve.

an intelligence score of 130.
