How factor analysis is used to reduce the data?
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.What is factor analysis for variable reduction?
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.- PCA and factor analysis are sister techniques to reduce the data from the higher dimensions to lower dimensional space without losing the information content of the data variance.

FACTOR ANALYSIS: A TECHNIQUE FOR DATA REDUCTION - CORE
It is easier to focus on some key factor rather than having to consider too many variables that may be trivial, and so factor analysis is useful for placing variables into meaningful categories Many other uses of factor analysis include data transformation, hypothesisǦtesting, mapping, and scaling (Rummel, 1970) |
