A factor analysis was conducted on 12 different characteristics of job applicants. This scree plot shows that 5 of those factors explain most of the variability because the line starts to straighten after factor 5. The remaining factors explain a very small proportion of the variability and are l...

Factor analysis (FA) and principal-components analysis (PCA) are two important multivariate statistical analysis methods. The two methods are often used together for data reduction by structuring many variables into a much smaller number of components or factors. The techniques are particularly useful ...
Factor Analysis is a statistical method used to explain the relationships among a group of test scores by identifying common factors and unique factors for each test. It can be used either to confirm or negate a hypothesized structure or to discover a structure in an exploratory manner. ...
