To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I purchased this book for a class in my MBA program. I last took Statistics back in college over 20 years ago and I did not remember much. I recently went back to school and I'm a bit rusty. This book is good but I found some of the explanations confusing. It is still a good book for basic statistics.
So i bought this book for my online statistics class, didnt open it once, it needs more excel explanations since thats where you do all statistics... otherwise the seller and delivery was perfect. skip buying if your going to college online. doesnt help at all.
