If you are taking this class, you should have taken stats 10 or 13 before, and if so, this class offers no new math. Having said that, it approaches the same material from the perspective of coding with R which can add a twist. I didnt do so hot on the quizes (B on all 4), however her midterm, homework and final made up for it. Her final literally had questions from the quizes. Also her poll everywhere kinda sucked, but i appreciate the sentiment of low cost materials. overall pretty chill if you are comfortable with stats 10 material.
