The process of statistical analysis is one of the most important problems facing most researchers in choosing the appropriate statistical method for statistical analysis in scientific research.

The purpose of this research is to provide a mechanism that allows the choosing of appropriate statistical methods and measures to process data of any type or Its nature and to be able to apply them skillfully in statistical analysis.

Where the method of selecting statistical measures depends on specifying the goal of the research and the hypothesis of the research that the scientific researcher wants to prove, such as if he wants to indicate the type and nature of the relationship between the variables or indicate the effect of a variable on another or needs to study what the phenomenon will be in the future, as well as the researcher to determine Its data type (where it is possible to classify it by its type, its level of measurement, or by the number of samples taken or by the number of variables) used in the research, as the nature of the data is what determines the type of statistical scale used, and to test the search data to indicate whether it is possible to apply to it Parametric and nonparametric.

The researcher designed an electronic questionnaire as a tool to collect information and distributed it randomly electronically (due to the existing ban due to the Corona pandemic) to Teaching staff Iraqi universities and institutes to show the most important problems of statistical analysis, and (100) forms were chosen after excluding the forms that were filled by professors who specialize Statistics as well as those who specialize in Arabic (because most of their research is theoretical and do not need statistical analysis in their research), and where most of the answers of research community Medium knowledge by statistical measures, their advantages and conditions of use, and they applied what they found followed in previous research, which is a large percentage.

Or they depend on the specialists and also we find that most of the sample members want to learn the basics of statistical analysis and how to choose the best scale in the statistical analysis of scientific research.

The researcher suggested to the scientific researcher to set the research goal and hypothesis first, and then determine the type of data used in the research, and then choose the appropriate scale for the type of their data and not rely on similar previous research.
