front 1 intelligence test | back 1 a method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores |
front 2 achievement test | back 2 a test designed to assess what a person has learned |
front 3 aptitude test | back 3 a test designed to predict a person's future performance; aptitude is the capacity to learn |
front 4 mental age | back 4 a measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance. Thus, a child who does as well as the average 8-year-old is said to have a mental age of 8 |
front 5 Stanford-Binet | back 5 the widely used American revision of Binet's original intelligence test |
front 6 intelligence quotient (IQ) | back 6 defined originally as the ratio of mental age to chronical age multiplied by 100. On contemporary intelligence tests, the average performance for a given age is assigned a score of 100 |
front 7 Wechsler Adult Intelligence Scale | back 7 the WAIS is the most widely used intelligence test; contains verbal and performance (nonverbal) subtests |
front 8 standardization | back 8 defining meaningful scores by comparison with the performance of a pretested group |
front 9 normal curve | back 9 a symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean, or average, and fewer and fewer near the extremes |
front 10 reliability | back 10 the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, or on retesting |
front 11 validity | back 11 the extent to which a test measures or predicts what it is supposed to |
front 12 content validity | back 12 the extent to which a test samples the behavior that is of interest (such as a driving test that samples driving tasks) |
front 13 predictive validity | back 13 the success with which a test predicts the behavior it is designed to predict; it is assessed by computing the correlation between test scores and the criterion behavior |
