Final answer:
People are considered gifted in terms of intelligence with an IQ above 130. This score signifies superior intelligence and places them in the top 2% of the population. IQ tests are crucial in assessing intellectual abilities and determining the need for additional educational support.
Step-by-step explanation:
People are termed gifted in terms of intelligence if their IQ is above 130. This places them in the top 2%, demonstrating a superior level of aptitude for learning and intellectual capability. The history of IQ test development can be traced back to the late 1800s, with significant contributors such as Sir Francis Galton and Alfred Binet. The American researcher Lewis Terman adapted Binet's work, resulting in the widely recognized Stanford-Binet Intelligence Scales.
Terman's longitudinal study in 1921 observed over 1500 children with high IQ and refuted the stereotype that individuals with high intelligence were maladjusted. Similarly, modern organizations such as Mensa require members to have IQ scores in the top 2% of the population, validating intellectual excellence.
IQ scores are gauged on a bell curve, where the mean or average score is set at 100, and each standard deviation is 15 points. Consequently, an IQ score of 130 or above signifies superior intelligence.
Regarding real-world applications, IQ tests such as those Candace underwent, reveal key insights into a person's intellectual capacities yet are not the sole determinants of success or potential within educational systems. These tests are also applied to ascertain whether additional educational support may be required, as in the case of a score indicating an intellectual disability.
