3. Setup Big Data Development Environment
This is another course from Udemy that helps you understand big data development. These big data course is for both Mac and Windows but does require a personal computer with a minimum of a 64-bit operating system and 16GB RAM.

5. Probability & Statistics
Many colleges offer a selection of courses online for free, and this course is just one great example. Carnegie Mellon University offers a probability and statistics course that teaches students the basic concepts of statistical reasoning. The course provides text, simulations, case studies, tests, and more. You will need your own copy of Microsoft Excel, Minitab (the open source R Software), TI calculator, or StatCrunch, however. Keep in mind that this course may be longer than the others on this list since it is equivalent to one semester of a college statistics course.
