The blogs on this Big Data page reach far beyond the material covered in the Big Data eCourse. They draw on my extensive professional experience in research as well as the many ways data shapes everyday life. The Big Data eCourse itself was developed by me and another teacher, and I am also one of the two correctors who assess the homework. Built on my career in data, the course provides a solid foundation, while the blogs offer deeper insights, practical examples, and broader perspectives. Each blog is organized by category and, within those categories, arranged alphabetically to help readers easily explore the topics that interest them most.
