About this career
Data scientists go beyond reporting on what happened — they build models that predict what will happen next. The role mixes statistics, programming (often Python or R), and a healthy dose of curiosity. Strong roles usually require a bachelor's-level math foundation, but you can start exploring the field with free online courses and projects long before then.
