A textbook in statistics should be written to such a standard that it does what it claims on the cover i.e. it should teach statistics. Undergraduate students who use other textbooks to study statistics typically find themselves lost within minutes or even seconds! What's the point of buying such a textbook if it doesn't teach? This was the inspiration for writing this textbook. The objective was to write a textbook that enables a student to learn statistics from a book. This book achieves that objective!

Learning statistics is easy if the material is presented well. This book adopts a step by step approach to learning statistics. The approach is non-theoretical and the material is taught through worked examples. The writing style is exciting and fresh and reflects the authors' style of teaching. A companion website is also provided which includes the following:

  • A step by step guide in the use of the computer software packages Minitab, SPSS and Excel.
  • Complete solutions to all odd numbered questions in the book.

The book represents the finished product of ten years of work. To investigate it's worth it has been tested on different groups of students. Students were asked to read certain sections/chapters and to put their hands up if they experienced difficulties in understanding the material. No hands were raised! When the students had completed a section they were asked to answer the questions at the end of that section. This is the true acid test for any book. The results - approximately 92% of students answered the questions correctly while the other 8% made small/silly mistakes. This book "does what it says on the tin" i.e. it teaches statistics. Irrespective of your college discipline, be it statistics, biostatistics, medicine, mathematics, business, economics, engineering, science, psychology etc. this book is a must for a student studying a first/intermediate course in statistics.
