Query: This is not for those without background in Statistics

My class uses this for our Statistics class and considering most of us have had StatisticsIn our prior college education (we had to repeat it bec its over 10 yrs), id say it stoill didnt make it easy to understand. I remember in one of the earlier pages, it omitted a very important step in calculating the Variance, thus, my group missed some points. Also the explanations are too abbreviated, in my opinion. I loathe this book.
