When you think of data science and its applications, you may think of a world where artificial intelligence and data meet to solve real-world problems. This view is somewhat accurate, but it only represents a small fraction of data science’s many purposes and use cases. Data science is an interdisciplinary field that combines computer science, statistics and mathematics to analyze data sets and find insights across a variety of software platforms and databases, businesses, industries and levels of complexity.

Data scientists focus on collecting and cleaning data, analyzing data sets using different statistical methods, visualizing the data to identify patterns and using insights to solve problems.

With their broad range of in-demand skills, the expected job growth for data scientists is incredibly promising. According to the U.S. Bureau of Labor Statistics, data scientist employment opportunities are expected to increase 36% between 2021 and 2031, which is well above the 5% average for all professions.

If you’re new to or simply curious about the data science field, many top tech organizations and universities offer data science training to help you get started. However, selecting the right course for your experience level and goals can be daunting. To guide you in your data science learning and development, we’ve put together a list of some of the best data science courses on Coursera, covering a range of specialties and skill levels.
