Data Jobs: What does a Data Analyst Do?


Data Analysts get a bad wrap. With the advent of the Data Scientist, Data Analysts are often viewed as Data Scientists lite, however I feel that is not the honest case. Truth is, there is a lot of overlap between the two fields. I will dive deeper into what a Data Scientist is in a future article, but just know my opinion is the definition of Data Scientist as a job is still a bit fuzzy and I think the job title may eventually be broken into a few different titles to better define the differences.

So what does a Data Analyst do?

A lot actually. You could put 10 data analysts into a room and you would get ten different answers to this question. So the best I can do here is make sweeping generalities. As the old saying goes “Your results may vary”

In general, data analysts perform statistical analysis, create reporting, run ad-hoc queries from data warehouses, create data visualizations, create and maintain dashboards, perform data mining, and create machine learning models (yes, ML is not only for data scientists). Their assignments are business driven. A data analysts is either embedded with a business unit (financial planning, fraud, risk management, cyber security, etc.) or working in a centralized reporting/analytics team. They use their skills to provide reporting and analytics for the business.

Educational Requirements

Typically a data analyst position will ask for a bachelors degrees, preferably in computer science, statistics, database management or even business. While the barrier to entry for a data analyst job is generally not as high as a data scientist, that does not mean you cannot make a meaningful and well paid career as a data analyst. Also, the demand for data professionals seems to keep going up and up and it most likely will for the foreseeable future.
