Charles Spearman is widely recognized for his pioneering use of factor analysis.
Spearman, a British psychologist, developed factor analysis in the early 20th century to study human intelligence.
He believed that intelligence was not a single, unified ability but rather a collection of underlying mental abilities, or factors.
Spearman's groundbreaking work led to the development of the two-factor theory of intelligence, which posits that general intelligence (g) is a fundamental cognitive ability that underlies all other mental abilities.
Factor analysis remains a powerful statistical technique used in various fields, including psychology, education, and sociology, to identify underlying structures in complex data sets.
