 FACTOR ANALYSIS 
  Factor analysis can be applied in order to explore a content area, structure a domain, map unknown concepts, classify or reduce data, illuminate causal nexuses, screen or transform data, define relationships, test hypotheses, formulate theories, control variables, or make inferences. 
  Factor analysis thus fulfills some functions of the laboratory and enables the scientist to untangle interrelationships, to separate different sources of variation, and to partial out or control for undesirable influences on the variables of concern. 
  Factor analysis is a mathematical tool as is the calculus, and not a statistical technique like the chisquare, the analysis of variance, or sequential analysis.
