CMN 170 Lecture Notes - Lecture 7: Predictive Policing, Chessboard, Homophily
Document Summary
Empirical because surveys are observational tools , in a sense that you observe the opinion of people empirically. Ex: charles darwin = traveling 5 years on famous beagle to observe beak of finches in galapagos island through empirical data; later he had a theoretical data deduced from his empirical data. Question: the empirical leg of science is quantitative, while the theoretical leg is qualitative. False; theoretical work can be qualitative, but most successful scientific theories are very quantitative (ex: einstein"s formulas) empirical methods often use statistics (quantitative) and theoretical methods often use pure math (also quantitative) Big data crystal ball = big revolution of digitalization in regards to empirical work. Analyze digital footprint (based on what happened in the past) Deterministically tells us how the future will happen under that assumption that it is very similar to past history. Computer simulations digital magic wand = big revolution of digitalization in regards to theoretical work simulations.
