Statistics and probability

Whilst I am not able to give you the exact breakdown I can share with you the path I followed.

I studied economics at grad level, so I did learn many of the calculus topics. But when I started to learn computer science after an early retirement from work I realized I needed to brush up my basic math skills. The path I followed was

Algebra II  > Pre-calculus > Diff calculus > Integral cal

I did Geometry II and Probability and statistics too.

Once you complete Khan Academy topics, you might find the EdX MITx and MITx OCW courses deepen your understanding of the subject matter.

I did every video, article, and practice exercise and all or most of the unit tests for High School Statistics, AP Statistics, and Statistics and probability on Khan Academy and finally finished them earlier this week. So this is fresh on my mind.

What I found is that algebra, at least Algebra I/1/One, is important because there is a lot of material on slopes and other aspects of graphing. Calculus is helpful but apparently not required because sometimes Sal will say in a Statistics video something like, “If you have taken calculus, you will recognize this concept from....” Precalculus here on Khan Academy contains a section on Probability that may be useful to try first. It may be a duplicate of what’s in the actual Statistics courses, or it may be more basic material that lays a foundation for the more advanced stuff in the Statistics courses.
