What does a data analyst do?
A data analyst helps businesses make informed decisions by transforming complex datasets into actionable intelligence. They bridge the gap between raw information and strategic outcomes, enabling organizations to identify opportunities, mitigate risks, and optimize performance.
Core responsibilities for data analysts include:
- Data collection and extraction. Gathering data from databases, APIs, spreadsheets, and third-party platforms using SQL and other query languages
- Data cleaning and preparation. Ensuring data quality by correcting errors, removing duplicates, handling missing values, and standardizing formats
- Statistical analysis. Applying statistical techniques to identify trends, patterns, correlations, and anomalies within datasets
- Data visualization. Creating interactive dashboards and reports using Tableau, Power BI, or Python libraries
- Predictive modeling. Developing forecasting models to anticipate future trends and business outcomes
- Business recommendations. Translating findings into actionable recommendations that drive measurable results
- Cross-functional collaboration. Working with marketing, finance, and operations teams to deliver customized analytical solutions
Data analysts work across technology, finance, health care, e-commerce, manufacturing, and government, helping businesses optimize campaigns, improve retention, streamline supply chains, and detect fraud.

Step 2: Filter and evaluate candidates
A systematic approach to candidate evaluation helps ensure you identify data analysts who have both the technical capabilities and communication skills your project requires. Focus on tangible evidence of past success rather than relying solely on self-reported expertise.
