But what exactly do data analysts do, and what skills and courses should you pursue to embark on a successful career in this field?
What do data analysts do?
Data analysts are responsible for collecting, organizing, and analyzing large sets of data to identify patterns, trends, and insights that can be used to drive business decisions.
