Final answer:
The fact that correlations correspond to cosines of angles between vectors in factor analysis has allowed researchers to create a visual, geometric interpretation of factor loadings. The correct answer is B) Develop a geometric interpretation of factor loadings.
Step-by-step explanation:
The fact that correlations correspond to the cosines between angles has allowed researchers who use factor analysis to develop a geometric interpretation of factor loadings.
In factor analysis, the correlation between variables can be represented geometrically as the cosine of the angle between two vectors in a multidimensional space. Each vector represents a variable, and the smaller the angle between them, the greater the correlation.
This geometric interpretation provides a visual way to understand how variables are related within a factor model, and it can be particularly useful for understanding complex data sets with many variables.
A strong correlation (represented by a cosine close to 1 or -1) would indicate a small angle and therefore a high factor loading, showing a strong association between a variable and a particular factor.
