The role of maths and statistics in the world of web analytics is not clear to many marketers. Not many talk or write about the usage of statistics and data science in conversion optimization. This book has been written to fill this knowledge gap. Often big heavy books on maths and statistics teach you more than you need to know, you learn things that you may never use in your working life. Not only do these books waste your time and money but they also constantly push you to give up on learning key maths and statistics skills. This expert guide will teach you exactly what you need to know. It will teach you how to leverage the knowledge of maths and statistics in order to accurately interpret data and take actions which can quickly improve the bottom-line of your online business. Every topic that I have covered in this book has something to do directly with your day to day job. This is not a book that will help you to become a fully-fledged statistician or a book to be used to pass your maths/statistics college exam.
