Detailed explanation-1: -a statistical procedure that identifies clusters of related items (called factors) on a test; used to identify different dimensions of performance that underlie one’s total score. a method for assessing an individual’s mental aptitudes and comparing them with those of others, using numerical scores.
Detailed explanation-2: -Factor analysis is a technique that is used to reduce a large number of variables into fewer numbers of factors. This technique extracts maximum common variance from all variables and puts them into a common score. As an index of all variables, we can use this score for further analysis.
Detailed explanation-3: -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-4: -A statistical procedure that identifies clusters of related test items that seem to tap a common ability is called. factor analysis. Factor analysis has been used to assess whether. intelligence is a single trait or a collection of distinct abilities.
Detailed explanation-5: -Factor analysis can be used more generally to identify multiple unobserved variables, or factors, that explain the correlations among our observed variables.
