Data analysts and data scientists: What do they do?
One of the biggest differences between data analysts and scientists is what they do with data.
Data analysts typically work with structured data to solve tangible business problems using tools like SQL, R or Python programming languages, data visualization software, and statistical analysis. Common tasks for a data analyst might include:
- Collaborating with organizational leaders to identify informational needs
- Acquiring data from primary and secondary sources
- Cleaning and reorganizing data for analysis
- Analyzing data sets to spot trends and patterns that can be translated into actionable insights
- Presenting findings in an easy-to-understand way to inform data-driven decisions
Data scientists often deal with the unknown by using more advanced data techniques to make predictions about the future. They might automate their own machine learning algorithms or design predictive modeling processes that can handle both structured and unstructured data. This role is generally considered a more advanced version of a data analyst. Some day-to-day tasks might include:
- Gathering, cleaning, and processing raw data
- Designing predictive models and machine learning algorithms to mine big data sets
- Developing tools and processes to monitor and analyze data accuracy
- Building data visualization tools, dashboards, and reports
- Writing programs to automate data collection and processing
