The most representative members of a concept are known as prototypes.

45. Copyright ©2012 by Pearson Education, Inc. All rights reserved. Psychology, Third Edition Saundra K. Ciccarelli J. Noland White Figure 7.4 The Normal Curve The percentages under each section of the normal curve represent the percentage of scores falling within that section for each standard deviation (SD) from the mean. Scores on intelligence tests are typically represented by the normal curve. The dotted vertical lines each represent one standard deviation from the mean, which is always set at 100. For example, an IQ of 115 on the Wechsler represents one standard deviation above the mean, and the area under the curve indicates that 34.13 percent of the population falls between 100 and 115 on this test. Note: The figure shows the mean and standard deviation for the Stanford-Binet Fourth Edition (Stanford-Binet 4). The Stanford-Binet Fifth Edition was published in 2003 and now has a mean of 100 and a standard deviation of 15 for composite scores.
