The purpose of the book; The aim is to provide researchers with the skills to choose an appropriate statistical test in the analysis of quantitative data, to apply the chosen test by following the correct steps, and to explain and interpret the results of the analysis. This was taken into account in the creation of the content of the book. Statistical test selection is the first and most important step in the data analysis process. The validity and reliability of the application of the selected test and the subsequent comments depend on the correct test selection. Therefore, test selection is considered as the first section. Each section describes the specific conditions for choosing that test. The book includes parametric tests and non-parametric tests, which are thought to be widely used in the field of Educational Sciences. The sample applications of the tests were based on the problem situations that could be the subject of research in the field of Educational Sciences, and the analyzes were made in the SPSS-21 program on the data produced. The outputs of the analysis were explained, sample tables of these outputs that could be included in the research report were created and the data were interpreted.
Detailed theoretical information is avoided in the book, and the sample applications given are supported with explanations. In the analysis steps and explanations, possible difficulties that the researcher may encounter were taken into account as much as possible, “do your own thing” without the help of anyone else. A way to serve the understanding has been followed. It is hoped that the work will be beneficial to academicians working in the field of Social Sciences in general, and educational sciences in particular, and researchers who are doing postgraduate studies, and will guide our teachers, who are in search of excellence, to overcome the problems they encounter while doing research in the teaching process.
