The minify factors can also be used for further analysis.
thither be three stages in factor analysis:
1. First, a correlation ground substance is generated for all the variables. A correlation matrix is a rectangular array of the correlation coefficients of the variables with each other.
2. Second, factors are extracted from the correlation matrix based on the correlation coefficients of the variables.
3. Third, the factors are rotated in order to maximize the relationship betwixt the variables and some of the factors.
Example
You may be interested to investigate the reasons why customers buy a product such as a particular brand of soft drink (e.g. coca cola).
