Detailed explanation-1: -Which pair of family members is likely to have the most similar IQ scores? Identical twins.
Detailed explanation-2: -The most widely used intelligence tests include the Stanford-Binet Intelligence Scale and the Wechsler scales. The Stanford-Binet is the American adaptation of the original French Binet-Simon intelligence test; it was first introduced in 1916 by Lewis Terman, a psychologist at Stanford University.
Detailed explanation-3: -Reliability is the ability of a test to produce consistent and stable scores. The simplest way to determine a test’s reliability is to give the test to a group and then, after a short time, give it again to the same group. If the group scores the same each time, the test is reliable.
Detailed explanation-4: -Advantages of twin studies Twin studies allow disentanglement of the shared genetic and environmental factors for the trait of interest. Researchers can estimate the proportion of variance in a trait attributable to genetic variation versus the proportion that is due to shared environment or unshared environment.
