What’s the difference between a Data Scientist and a Data Analyst in 2023?

Businesses are dealing with more and more data each day. This is so much to the extent that there’s an increasing demand for jobs requiring data skills. There's been an explosion of the amount of data generated in almost every department from marketing, product, sales, to HR and finance.
Data-driven talents with analytics, machine learning, and artificial intelligence skills are in demand from employers. Both data scientists and analysts are in need, with incomes often above the national average, since the world relies more and more on data in business, research and the economy. To support this, you may have noticed that Le Wagon recently launched an all-new Data Analyst Bootcamp and are now accepting applications for our January Bootcamps. At the same time, our Data Science Bootcamp is still an increasingly popular choice when selecting a course to develop new tech skills.

So, you may be asking yourself, which career path is right for me? Although there’s no right or wrong answer, we hope to clarify the difference between the two job roles so you can make the right choice for a career path that satisfies your needs and goals.

What is a Data Scientist?
A data scientist oversees gathering, analyzing, and interpreting data to support decision-making inside a company. A mathematician, scientist, statistician, and computer programmer are just a few of the traditional and technical vocations combined into a data scientist’s function. It combines scientific ideas with cutting-edge analytics methods like machine learning and predictive modeling.

Data scientists often mine data in firms to find information that may be utilized to forecast consumer behavior, find new revenue opportunities, spot fraudulent transactions and fulfill other company needs. Additionally, they perform crucial analytical work for healthcare organizations, educational institutions, governmental bodies, sports teams, and different organizations.

What is a Data Analyst?
By interpreting various data, data analysts assist organizations in understanding the state of the business today. Data analysts draw conclusions from data to describe, predict, and enhance business performance using methods from a variety of disciplines, such as computer programming, mathematics, and statistics. Any analytics team’s core consists of these individuals, typically generalists skilled in mathematical and statistical analysis techniques.

By converting data into valuable knowledge for business, data analysts aim to describe the existing reality within their organizations. They gather, examine, and present data to satisfy business requirements. Finding new data sources and methods to enhance data collecting, processing, and reporting is part of the job description. Data analysts work to assist company leaders in making tactical decisions through reporting and impromptu queries, whereas data scientists are frequently involved in long-term study and prediction.
