The book describes quantitative and qualitative research methods, as well as the process of writing scientific papers. Although it is rich in information and technical details, it is written in an accessible way to be understood by both students and researchers with experience in the field. In the 3rd edition, ethical issues were added and the content was expanded to cover more aspects of scientific research through the various forms of scientific papers, the creation, review, and publication of scientific texts, the types of scientific publications, and the process of submitting articles to academic journals. One of the advantages of the book is its holistic approach. It describes the presentation of literature reviews, the formulation of research questions and hypotheses, research design, data collection and analysis, writing results, and discussing findings. It focuses on preparation, data collection, exploring existing knowledge through literature, using secondary data, and conducting quantitative research with structured questionnaires, while examining reliability, validity, sampling methods, and statistical analyses.
