What is data analytics?
Data analytics turns data into insights that help businesses decide.
📖 Key ideas
- Analytics answers business questions using data.
- Four types: descriptive (what happened), diagnostic (why), predictive (what will happen), prescriptive (what to do).
- Data analysts clean, analyse, visualise and present data.
- Tools: Excel, SQL, Power BI/Tableau, Python.
- Every industry uses analytics: retail, banking, health, education.
