A Practical Introduction to Applied Statistics for Materials Scientists and Engineers
Keffer, David J.
Synopsis "A Practical Introduction to Applied Statistics for Materials Scientists and Engineers"
Materials Scientists and Engineers work in a quantitative field in which the mechanical, thermodynamic, rheological and electronic properties of the materials are described with numbers. Therefore, a basic proficiency in applied statistics is necessary to be able to interpret and communicate the significance and reliability of these numbers. The numbers provide the technical basis upon which are made engineering decisions that impact the successful deployment of the material and ultimately the success of the project, including many elements such as public safety. Understanding the statistical confidence in these numbers is therefore of practical significance. This book provides a practical but fundamental mathematical understanding of applied statistics and the theory of probability that underlies it. This book is targeted at undergraduates. It is used in a course during the third year that covers both applied statistics and numerical methods. Thus, the contents herein are intended to cover half of one semester. The content is divided into six chapters (or modules), covering (1) probability, (2) random variables, (3) expectations, (4) discrete distributions, (5) continuous distributions and (6) sampling and estimation. Other important statistical procedures, such as regression, are covered in the second half of the course, numerical methods. The philosophy espoused in this book is to equip the student with a compact but broadly applicable set of practical problem-solving tools such that the student emerges at the end of the course with the ability to clearly articulate the statistical reliability of the numbers used to describe the materials of interest. Finally, we live in a world where the importance of literacy, the ability to make sense of words, is taken for granted. At the same time, importance of numeracy, the ability to make sense of numbers, is neglected. In fact, poor numeracy skills of the general public (and its elected leaders) are regularly exploited, both intentionally and unintentionally, particularly by those who seek to sway public opinion. An introduction to applied statistics is the first step toward the ability to extract meaning and significance from raw data. In this book, the application of these techniques is toward materials science. However, the broader applicability of such techniques is a natural consequence of one equipped with these skills.
