Saya mau tau Kapunjulan dari Analisis faktor. Jelaskan dalam bahasa sunda

Offers a much more objective method of testing intelligence in humans

Allows for a satisfactory comparison between the results of intelligence tests

Provides support for théories that would be difficult to prove otherwise

"...each orientation is equally acceptable mathematically.  But different factorial theories proved to differ as much in terms of the orientations of factorial axes for a given solution as in terms of anything else, so that model fitting did not prove to be useful in distinguishing among theories." (Sternberg, 1977).  This méans that even though all rotations are mathematically equal, they all come up with different results, and it is impossible to judge the proper rotation.

"[Raymond Cattell] believed that factor analysis was 'a tool that could be applied to the study of behavior and ... might yield results with an objectivity and reliability rivaling those of the physical sciences (Stills, p. 114).'"    In other words, one’s gathering of data would have to be perfect and unbiased, which will probably never happen.

Interpreting factor analysis is based on using a “heuristic”, which is a solution that is "convenient even if not absolutely true" (Richard B. Darlington). More than one interpretation can be made of the same data factored the same way.
