The terms “data analyst” and “data scientist” are often used interchangeably, as both jobs are critical when it comes to analyzing corporate data in meaningful ways. However, the jobs themselves are actually quite distinct. Each comes with different responsibilities and each job title requires unique qualifications. So just what are the differences between the two?
What is a Data Analyst?
Data analysts are tasked with collecting, manipulating, and of course, analyzing data. They take that data and prepare reports which detail their results. Analysts are also responsible for guarding and protecting the data they work with. Data analysts almost always hold bachelor’s degrees, and many have master’s degrees in business intelligence specializations. If they continue their education, many data analysts move on to become data scientists.

Data scientists hold master of science and PhDs in subjects like math, statistics, operations research, or machine learning. They also go a step beyond technical expertise, and many also hold MBAs. Why? Strong business acumen is required in order to effectively address business problems. Data scientists have to be able to communicate their findings with IT leaders and other non-technical business leaders, as their work influences the way an organization makes decisions and approaches problems.
