Data analysts turn raw information into clear findings that support business decisions. Strong analysts combine technical skills with the ability to ask useful questions and communicate results to non-technical teams.
Build a balanced skill set
- Use Excel for cleaning, formulas, lookup functions, and pivot tables.
- Write SQL queries to filter, join, aggregate, and validate data.
- Create clear dashboards with Power BI or another visualization tool.
- Understand descriptive statistics and basic data quality checks.
- Explain insights using business-focused language.
Choose portfolio projects with a clear question, documented cleaning steps, a concise dashboard, and actionable conclusions. A focused project often demonstrates your ability more effectively than a collection of disconnected charts.
