This textbook was extremely helpful for me to understand the concepts behind the complicated formulas in statistics. It has a lot of worked examples using real world problems. I recommend this to professors.
I barely used it. Definitely not worth the $300 if I'm only going to be using my lecture notes, right? I never once used the software aid that came with it, either. It was only a 3 credit class. Yeah, the schools need to quit making us waste our money on a textbook that is "required" for a class.
