This is the evolution of a bivariate correlation between two questionnaire scales, "hope of power" and "fear of losing control". Both scales were administered in an open online study. The video shows how the correlation evolves from r = .69*** (n=20) to r = .26*** (n=271). It does not stabilize until n = 150.
