In a news bulletin, University of California, Berkeley announces that its "Foundations of Data Science" course is "being offered free online this spring for the first time through the campus's online education hub, edX." From the report: The course -- Data 8X (Foundations of Data Science) -- covers everything from testing hypotheses, applying statistical inferences, visualizing distributions and drawing conclusions, all while coding in Python and using real-world data sets. One lesson might take economic data from different countries over the years to track global economic growth. The next might use a data set of cell samples to create a classification algorithm that can diagnose breast cancer. (Learn more from a video on the Berkeley data science website.) The online program is based on the Foundations of Data Science course that Berkeley launched on campus in 2015 and now has more than 1,000 students enrolling every semester. The Foundations of Data Science edX Professional Certificate program is a sequence of three five-week courses taught by three winners of Berkeley's top teaching honor, the Distinguished Teaching Award: DeNero, statistics professor Ani Adhikari and computer science professor David Wagner. The first of the three parts has already started (9 a.m. on April 2), but enrollment will remain open after the course begins. Furthermore, anyone in the world can enroll for free but those who want to earn the certificate will need to pay.
