It highlights the most famous statistical methods, which is ANOVA. This method depends on number of assumptions, which consider being the most important ones in order to obtain accurate results. So, this study aims to diagnosis the reality of this method, and to clarify mistakes of researchers at using this method. The misuse of this method leads to wrong mistakes, upon which the one cannot depend on. The researcher has used the analytical descriptive method. The sample of the study consists of 130 theses; 106 of them are master thesis, and 24 are PhD theses. The sample has been selected by the cluster method. The community of the study has been divided into two sections (Master and PhD theses). Then, the researcher has been divided into ten sections according to the time of each research. Random sample has been selected from each research. The researcher designed and prepared tool of the study in order to collect information about the sample of the study. This tool includes information about type of data, the used analysis, descriptive data, and testing assumptions of variance analysis, post comparison and the appropriateness of analysis validity. Questions of the study: What is the type of the used data and ANOVA in master and PhD researches in College of Education, Umm Al-Qura University? What is the extent of masking sure from the assumptions of ANOVA in master and PhD theses in College of Education, Umm Al-Qura University? What is the extent of fulfilling the required conditions when using the post comparisons in master and PhD theses in College of Education, Umm Al-Qura University? What is the extent of the appropriateness of the used ANOVA method in master and PhD researches in College of Education, Umm Al- Qura University? Results of the study: The study led to that the most of MA and PhD theses have used the method of ANOVA. There is defect in making sure of the appropriateness of using ANOVA IN studies. Master and PhD theses have used varying sizes in their samples there is defect in some studies concerning not making sure of the conditions of post comparisons, and making sure from its validity. There is difference between MA & PhD theses in making sure from the assumptions of ANOVA, and may be this is due to not knowing how to make this. (Published Abstract)
