Can anyone guide me through the steps in reading a table generated through factor analysis in SPSS. I threw some of my variables in to the factor analysis data reduction table in SPSS, it ganarated three tables-communalities, Total variance and components. I would like to be able to read them and interpret them. Can someone guide me with a general idea. The tables by default generates PCA (principal component analysis) how can I do common factor analysis? Any help will be appreciated. Thanks Moushumi Hi Can anyone guide me through the steps in reading a table generated through factor analysis in SPSS. ..... it ganarated three ...
In other words, it is possible, for example, that variations in three or four observed variables mainly reflect the variations in a single unobserved variable, or in a reduced number of unobserved variables. Factor analysis searches for such joint variations in response to unobserved latent variables . The observed variables are modeled as linear combinations of the potential factors, plus " error " terms. The information gained about the interdependencies between observed variables can be used later to reduce the set of variables in a dataset. Factor analysis originated in psychometrics , and is used in behavioral ...

WikiAnswers - Why use factor analysis and why is it important
Throughout math, you will use a process known as factoring in many different problems. It is used when solving polynomial equations, to simplify things, and many other purposes. Writing a polynomial as the product of two or more polynomials is called factorisation. If A = B x C, B and C are called factors of A. Most of the polynomials can be factorised by grouping the terms suitably and taking out the common factors. Another way to use factoring is to solve a quadratic equation by hussain alkadhimi ISGR MYP 9E First answer by ID1409172298 . Last edit by ID1409172298 .
