Berkeley News: “The fastest-growing course in UC Berkeley’s history — Foundations of Data Science — is being offered free online this spring for the first time through the campus’s online education hub, edX. Data science is becoming important to more and more people because the world is increasingly data-driven — and not just science and tech but the humanities, business and government. “You’ll learn to program when studying data science — but not for the primary purpose of building apps or games,” says Berkeley computer science Professor John DeNero. “Instead, we use programming to understand the world around us. ”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.)
