In this book applications of hypothesis testing for environmental science are
described in an easy and enjoyable style to help and assist graduate and postgraduate
students and researchers working in the fields of environmental science, environmental engineering, and related fields. The lack of knowledge of many researchers about
the concept and application of hypothesis testing in the environmental field, including how to state the hypothesis, how to choose the most suitable test, and how to
interpret and draw conclusions motivated me to write this book and introduce
hypothesis testing for one and two parameters covering three procedures for hypothesis testing (critical value, P-value, and confidence interval) and to connect the theory to the environmental field to meet the needs of researchers and enable them to
carry out various testing procedures and draw conclusions.
The concept of hypothesis testing, the type of test, interpretation of the results,
and drawing conclusions are carried out in a step-by-step, easy, and clear manner to
enable researchers to understand it clearly and use it in their research. The book
focuses on the application of hypothesis testing for one and two population parameters including Z-test, t-test, chi-square test, and F-test, which are frequently used
by researchers in the environmental field. Most of the tutorials in the book use real
data obtained through over 18 years of research in this area.
Finally, I wish to thank my beloved family for their continuous support. I also would
like to express my gratitude to University of Kuala Lumpur (Unikl) for its support.
