Detailed explanation-1: -Factor Analysis-Statistical procedure that identifies clusters of related items (factors) on a test; used to identify dimensions of performance that underlie a person’s total score.
Detailed explanation-2: -Factor analysis (FA) allows us to simplify a set of complex variables or items using statistical procedures to explore the underlying dimensions that explain the relationships between the multiple variables/items.
Detailed explanation-3: -Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors.
Detailed explanation-4: -Factor analysis is a statistical technique used to find major trends in large amounts of data. It seeks to find similarities, clusters, or groups of related items.
