Understanding IQ Scores
IQ scores measure cognitive abilities, assessing problem-solving, logical reasoning, and intellectual capacity. They are standardized, allowing comparison across individuals, and are widely used in education and employment assessments.
2.1 How IQ Scores Are Calculated
IQ scores are calculated by comparing an individual’s performance to a standardized average, typically set at 100. The calculation involves the mean and standard deviation of the test group, ensuring scores reflect cognitive abilities relative to peers. Higher scores indicate above-average intelligence, while lower scores suggest below-average performance. The process ensures consistency and comparability across different test-takers.
2.2 IQ Score Ranges and Categories
IQ scores are categorized into ranges, with an average score of 100. Scores below 70 are considered low, indicating intellectual disability. Scores between 70-84 are borderline, 85-114 average, 115-129 above average, 130-144 gifted, and above 145 highly gifted. These categories help classify cognitive abilities and guide educational or professional assessments, providing a framework for understanding individual intellectual potential.
2.3 Factors Influencing IQ Scores
IQ scores are influenced by genetic predisposition, education, socioeconomic status, and environmental factors. Emotional intelligence, nutrition, and access to cognitive stimulation also play roles. Cultural bias in test design can affect results, as can personal motivations and test-taking strategies. These factors highlight the complexity of measuring intelligence, emphasizing that IQ scores reflect a combination of innate and external influences.
Structure of IQ Tests
