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 analyzes reviews to verify trustworthiness.
This book is wonderful. This was required reading for my negotiation class and I am glad it was. The information is clear and written to be implemented immediately. Everyone should read this book to better identify opportunities to negotiate and build better skills in negotiation.
