What Do Data Analysts and Data Scientists Do?
Understanding the core responsibilities of data analysts and data scientists can help determine their fit within your organization. While both roles revolve around data, their approaches and objectives differ significantly.
Role and Responsibilities of a Data Analyst
Data analysts focus on interpreting existing datasets to uncover trends and insights that drive business decisions. They primarily work with structured data, utilizing tools like Excel and SQL to process and analyze information. Additionally, data analysts create dashboards and visualizations using software such as Tableau or Power BI to present their findings in a user-friendly format. Their reports help businesses make informed operational and strategic decisions.
At its core, the work of a data analyst revolves around descriptive analytics. This involves examining historical data to answer the question, “What happened?” and providing clarity on past trends to improve current decision-making.
Role and Responsibilities of a Data Scientist
Data scientists adopt a more advanced and exploratory approach to data, using programming, statistical models, and machine learning techniques.
