What Can You Do With a Master’s Degree in Data Science?

A master’s degree in data science will give you both the theoretical knowledge and the practical skills you need to advance your career in this rapidly growing field.

Advancing your education in data science can help you develop important analytical, business, modeling, and visualization skills, as well as advanced programming and coding skills. You may learn cutting-edge trends in artificial intelligence, machine learning, and other developing technologies. Or you can explore new ways to apply your skills across different industries such as healthcare, advertising, wearable tech, or autonomous vehicles and drones.

Read more in our blog post What You Can Do with a Master’s in Data Science.

Is a Degree in Data Science Useful?

A degree in data science may not be required to get started in the field, especially for entry-level programmers and data analysts. Degrees in software engineering, computer science, math, and statistics can give you the basic skills you need to start a career in data science.

However, a graduate degree in data science offers a combination of skills that can help you stay competitive in the job market. In addition to programming and statistics, for example, a degree in data science offers advanced knowledge of modeling, data visualization, data analysis, and business intelligence.

Moreover, many mid- and senior-level positions such as data scientist or data architect for example, as well as most management positions, may require a master’s degree in data science.

Is a Career in Data Science a Good Career?

As organizations harness new technologies to gather and collect information more effectively, the demand for knowledgeable professionals with the skills to analyze that data correctly is growing—and quickly.

According to the US Bureau of Labor Statistics, jobs for data scientists and related positions are expected to grow 22 percent between 2020 and 2030.

And due to both growing demand and the complexity of the work, data science can be a lucrative career as well. According to Glassdoor, data science was the third-best job in the United States in 2022, based on median salary and availability of job openings.

How Long Does it Take to Complete the Data Science Graduate Program?

Program length is ordinarily anywhere between 2 and 5 years. It depends on your preferred pace and the number of courses you want to take each semester.

For an accelerated journey, we offer year-round study, where you can take courses in fall, January, spring, and summer.

While we don’t require you to register for a certain number of courses each semester, you cannot take longer than 5 years to complete the degree.
