Things get serious with this 21-hour course which provides a good introduction to the data science field and tools like SQL, SSIS, Gretl, and Tableau. The entire course is divided into learning modules (pathways) which you can follow as independent units, mix them up, or learn them all in one go. Look through the preview of the course structure explained in Lecture 5 to plan your attack.

The learning pathways are spread out over 200 lectures. They cover data visualization and data mining, statistical modeling, data preparation, and finally end with presentation skills. The course starts with data visualization which is always the most fun part of data science rather than data preparation which is the most ponderous.

The A-Z course balances a broader view of the entire field with the nitty gritty you need to get the handle on a complex data science project.
