Foreword
The speed of changes and transformations in all dimensions of life of human societies, on the one hand, today has made researches necessary for progress and elimination of deficiencies and shortcomings, and on the other hand, categorizing and classifying information and reporting them in the form of tables and graphs and using the applications of statistical science. , has made it easy for people in the society to understand and create connections between variables. Basic research provides thinking and solutions and answers to related questions and finding solutions. To carry out the research, it is necessary to know its components. To achieve this goal, it is necessary for researchers to know enough about the details of the research implementation. The two basic issues that researchers always deal with are methodology and statistical methods for data analysis, and these two provide useful tools for designing, implementing, and extracting results related to data from studies. Methodology, like any other science, deals with a set of theoretical concepts and until these concepts are investigated, measured and analyzed, it is not possible to discover the relationships between them for the purpose of making decisions and making predictions. Familiarity with the methodology and methods of statistical science provides the possibility of methodical and useful implementation of research, and the results are reported with precision, accuracy and accuracy, and users find the possibility of useful and necessary use of the results.
