The Assessment of Statistical Processes used in Published Educational Researches: Dar-Almandumah Database as a Model

Abstract

This research aims to study and assess the statistical processes used in the educational researches published in Dar-Almandumah database. Purposive sampling has been used in this study, which consisted of 301 educational researches classified into three categories. To achieve the objective of this research, the approach of Preferred Reporting Items for Systematic and Meta-Analysis Protocols (PRISMA-P2015) has been followed. It consists of three stages; the first covers abstracts, the second covers the statistical methods, and the third discusses verification of the assumptions related to the statistical methods used in the researches. Frequencies and percentages have been used in each of the three stages. The first stage concluded that: most of the educational researches’ abstracts did not mention the type of sample used, a few abstracts mentioned the size of sample and target population, most of the researches used the descriptive-analytical approach and qualitative data, and the independent variable was mentioned in the abstracts more than the dependent variable. The results of the second stage indicated that descriptive and simple inferential methods are used the most, whereas, the results of the third stage indicated a lack of verifying assumptions of the statistical methods used in the researches.
