Step 1: Understand the statistical purpose.
- Factor analysis is a statistical method that examines relationships among observed variables. - It identifies latent variables (factors) that explain patterns of correlations among measured variables.
Step 2: Analyze given options.
- Correlation: Measures relationship between two variables only. (Incorrect)
- Regression: Predicts one variable based on another. (Incorrect)
- Factor Analysis: Discovers underlying structure from loading patterns. (Correct)
- Item Analysis: Evaluates test questions, not loading patterns. (Incorrect)
Thus, the correct statistical technique is: \[ \boxed{{Factor Analysis}} \]
