Intelligence quotient (iq): a child"s mental age divided by chronological age, multiplied by 100. Factor analysis: correlations among many variables are analyzed to identify closely related clusters of variables. Fluid intelligence: involves reasoning ability, memory capacity, and speed of information processing. Crystallized intelligence: involves ability to apply acquired knowledge and skills in problem solving. Normal distribution: symmetric, bell-shaped curve that represents the pattern in which many characteristics are dispersed in the population. Deviation iq scores: locate subjects precisely within the normal distribution, using the standard deviation as the unit of measurement. Intellectual disability: subnormal general mental ability accompanied by deficiencies in adaptive skills, originating before age 18.
