# make data-driven decisions — Data Scientist

For a Data Scientist, 'making data-driven decisions' isn’t about *just* reporting KPIs; it's the core of how you justify recommendations and build impactful solutions. Daily tasks involve framing business problems as analytical questions (e.g., “How can we reduce customer churn?”), then designing experiments or analyses to answer them using relevant data – often requiring SQL for extraction, Python/R for manipulation & modeling, and visualization tools like Tableau or Power BI to communicate findings. It means going beyond descriptive statistics; you're building predictive models, running A/B tests, and quantifying the impact of potential changes *before* they’re implemented.
