All performance metrics (Selectivitat, English, attendance, etc., even “Prompt_response") positively correlated
Postponing_gratification (basic fundamental skill) positively correlates w. all metrics of performance
Risk_loving positively correlates with Socratic
Students with higher Selectivitat scores dislike Socratic
Economics students like Socratic more than ADE students
