prediction output correct answer: descriptive, predictive, prescriptive
challenges to data analytics correct answer: limited in its use,incompletely adhere to well-known standards, only allows observational and not experimental studies, research questions tend to b driven by what can b answered, not always as objective, "bigger" is not necessarily better, ethical concerns [Show Less]
