Detailed explanation-1: -Types of IQ Tests and Tasks The most commonly used test series is the Wechsler Adult Intelligence Scale (WAIS) and its counterpart, the Wechsler Intelligence Scale for Children (WISC). Other commonly used tests include the original and updated version of Stanford-Binet, and the Kaufman Assessment Battery for Children.
Detailed explanation-2: -*Validity-the extent to which a test measures or predicts what it is supposed to.
Detailed explanation-3: -Spearman is well-known for proposing the g factor, which refers to general mental ability. He observed that children’s school performance was essentially consistent across all school subjects, rather than being high in some subjects and low in others.
Detailed explanation-4: -IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120.
