Abstract EN

Field research often requires a statistical study, and for dealing with the field and taking from it certain controls that guide the researcher and help him to control the data for the sake of the accuracy of the analysis and thus the accuracy of the results.

And because there are problems that cover large societies, it is difficult to study all cases and the elements in them, and because this requires large costs that may hinder the continuation of the study, the researcher resorts to the sample method instead of the comprehensive survey method.

There are many types of samples and different sizes for them too; The choice of this type or this size determines several factors, including the nature of the phenomenon studied and the researcher's potential.
