Master in‑demand tech skills with these 6 certified, top-tier free courses

As a data analyst, your focus isn't on creating dashboards, writing SQL queries, doing pivot tables, generating reports, or cleaning data.

Your focus should be solving business problems using these skills

- Don’t just write SQL—ask why you're querying that data and what decision it will influence.

- Don’t just build a dashboard—ask who will use it and how it will help them take action.

- Don’t just clean data—know what insight lies beneath the mess.

- Don’t just report metrics—ask what story they’re telling and what recommendation can follow.
