Study Notes
Factor Analysis
- Factor analysis is a statistical method used to reduce a large set of variables into a smaller set of underlying factors that summarize the data.
Principal-Components Method
- The Principal-Components Method is a type of factor analysis used to extract the most important information from a large dataset and condense it into a smaller set of factors.
Guilford's Factor Analytic Approach
- Guilford's factor analytic approach focused on identifying the structure of cognitive abilities, particularly in the area of intelligence.
Cattell's Source Traits
- Cattell's Source Traits represented the underlying, stable aspects of personality that are relatively enduring and resistant to change.
NEO PI-R
