A Primer on Statistics
This course is meant to give you a high level introduction to the world of statistics, without requiring any prior knowledge besides basic math. Each chapter has several interactive visualizations of the new concepts to allow you to get your hands dirty.
The topics are presented with a good degree of mathematical rigor, but to ease the reading I have almost entirely avoided formal proofs. I have favored a wide ranging overview of what can be done with statistics rather than diving really deep into a single topic, which of course I encourage you to do if you find this subject interesting.
