Data science is becoming relevant to many different jobs, and ‘Data scientist’ has been been called the sexiest job of the 21st Century. So how do you become one?
A great way is by taking the Data Science Specialization, consisting of nine four-week courses, and a capstone course. In addition to a solid understanding of the fundamentals, it is focused on real-world practice, using real tools on real data, and results in tangible data products that can be seen by others.
Prof. Peng describes the sequence of topics in the Specialization in this video:

Through this Specialization, you will learn to use a variety of tools and have tangible results that you can put online, including your analysis code, documentation, and data products. Prof. Peng believes that this is a great way to demonstrate your skills to potential employers:
