Exploration of the Big Five: Dimensionality Reduction and Clustering Techniques

This study presents a comprehensive analysis of the BFI dataset using the 'psych' package in R. Through principal component analysis and descriptive statistical techniques such as PCA, histograms and Classification. We explored the dimensions of personality based on 25 evaluative items from the International Personality Item Pool. Columns A-E highlight the behavioral traits of agreeableness, conscientiousness, extraversion, neuroticism, and openness, measured on a 6-point response scale. The results provide significant insights into the correlations among different traits and offer a richer understanding of human personality dynamics.
