How to Become a Data Scientist: Roadmap & Timeline
Data scientists typically split their time between exploratory analysis, building and validating models, and translating findings into actionable business recommendations. A significant portion of the role — often underestimated — involves cleaning data, aligning with stakeholders on the right question to ask, and presenting results to non-technical audiences.
Step-by-Step Requirements
- Step 1: Master's or PhD in Statistics, Computer Science, Mathematics, or Economics preferred
- Step 2: Proficiency in Python and SQL — non-negotiable at most companies
- Step 3: Experience with machine learning frameworks (scikit-learn, TensorFlow, or PyTorch)
- Step 4: Portfolio of data projects with documented methodology and results
