Step 3: What criteria will assist in determining factor extraction?
The aim of the data extraction is reduce a large number of items into factors. In order to produce scale unidimensionality, and simplify the factor solutions several criteria are available to researchers. However, given the choice and sometimes confusing nature of factor analysis, no single criteria should be assumed to determine factor extraction.21 This is reinforced by Thompson and Daniel22, p.200 who stated that the “simultaneous use of multiple decision rules is appropriate and often desirable”.
