The difference in what a data analyst does as compared to a business analyst or a data scientist comes down to how the three roles use data.
At startups and other small organizations, it is not uncommon for a data analyst to take on some of the predictive modeling or decision-making responsibilities that may otherwise be assigned to a data scientist.
DATA ANALYST
serves as a gatekeeper for an organization’s data so stakeholders can understand data and use it to make strategic business decisions.
DATA SCIENCE
takes the data visualizations created by data analysts a step further, sifting through the data to identify weaknesses, trends, or opportunities for an organization.
BUSINESS ANALYST
serves in a strategic role focused on using the information that a data analyst uncovers to identify problems and propose solutions.
