What Does a Data Analyst Do?
A Data Analyst works with past and present data to help companies make better decisions. Their job is to turn raw numbers into clear insights that can be used for business strategies. Whether it’s sales, customer behavior, or performance tracking, a data analyst turns reports into action.

A data analyst career is ideal for those who love working with numbers, solving small business problems, and helping teams make decisions using facts.
What Does a Data Scientist Do?
A Data Scientist goes deeper into data. They don’t just look at what happened—they try to predict what will happen next. They use coding, statistics, and advanced math to build models and machine learning systems that find future patterns.
