Detailed explanation-1: -In factor analysis, we are concerned only with the variance that each variable has in common with the other variables, not with the unique variance. This technique uncovers patterns among variables and then clusters highly interrelated variables into factors.
Detailed explanation-2: -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-3: -Factor analysis is a powerful data reduction technique that enables researchers to investigate concepts that cannot easily be measured directly. By boiling down a large number of variables into a handful of comprehensible underlying factors, factor analysis results in easy-to-understand, actionable data.
Detailed explanation-4: -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-5: -Factor analysis is a term used to refer to a set of statistical procedures designed to determine the number of distinct unobservable constructs needed to account for the pattern of correlations among a set of measures.
