Foreword

The book “Probability and Statistics: Theory and Exercises” by Dr. Horimek Abderrahman, is an excellent scientific contribution, written in a simple, clear English language. Presented in practical, user-friendly, and relevant manner, this book will enable engineering and science students and teachers to understand the concepts and theories of probability and statistics and apply them in real-life situations. This is a real contribution to spreading the culture of statistical thinking among the Algerian higher education community and business leaders in the country.

Statistical thinking has been adopted by world-class organizations as a way of understanding our complex world by describing it in relatively simple figures that capture essential aspects of its structure and components. Statistical thinking, through probability and statistics, provides us with evidence about our past and present and allows us to discover insights into the future. Through statistics, evidence-based decision-making processes can be established, so higher product or service quality can be delivered to customers; hence contributing to an improved Quality of Life. Indeed, statistics have been used to predict future events, and foresight even the future of nations and citizens, hence contributing to build a sustainable future.

As statisticians, we always refer to the famous statement from H.G. Wells, “Statistical thinking will one day be as necessary for efficient citizenship as the ability to read and write.”, I would rather say that this event is already happening, and we need to dig deeper in this science through this book and other reference textbooks.

It is expected that this manuscript will be a useful guide for all individuals who are involved in studying events and phenomena related to social, technical, engineering, or medical sciences.
