Data Science 101

Data Science 101, course code DS0101EN, is an orientation course rather than a technical one. The Cognitive Class page states an estimated effort of 11 hours at beginner level, in English, with no prerequisites or recommended skills, and describes it as self-paced. Its five modules move from defining data science, through what data science people do, data science in business, use cases for data science, and finally the people who work in the field. The material is built around interviews with practitioners telling stories about their work, alongside short readings on topics such as the difference between R and Python, regression, the final deliverable and how a report is structured.

The course was produced by Fireside Analytics, an education company that develops data-literacy courses. There is no coding; the aim is to help you decide whether data science is for you and what to learn next. The course is free of charge and the page says a certificate is offered on completion, which the platform provides at no cost. The page notes the course was formerly named Data Science 101, so you may see it referenced under that title elsewhere.
