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 visualizations 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.

A master’s degree in data science may open a variety of exciting opportunities in this expanding field.

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?

The data science graduate program at Harvard Extension School offers maximum flexibility so that professionals with demanding schedules can design their own path.

Interested in an accelerated journey? Enroll in consecutive terms or take multiple courses in a term. For a more moderate pace, you can take one course per term and even take a term off if you need to.

Most students take one or two courses each term. Once you complete the two courses required for admission, you have five years to complete the final eight courses and your capstone project.

What Prerequisites Do You Need Before Applying for the Data Science Master’s Degree Program?

With Harvard Extension School’s unique “earn your way in” admissions process, there are no prerequisites required to begin your course of study in the data science master’s degree program.

To get started, you must complete two required courses that apply toward your degree: Foundations of Data Science and Engineering (CSCI 101) and Data Modeling (CSCI 106) or Introduction to Statistical Modeling (STAT 109).

However, to qualify for the master’s program, you must have prior knowledge of calculus and be able to write functions in Python and R. If you do not have these skills, it is recommended that you take Python (CSCI 7), Programming in R (CSCI 5A), and/or Calculus (MATH 15) before starting the degree program.
