This research aims to make a comparison between two methods of discrimination or classification, namely the logistic regression method and the method of discriminatory function, and this comparison was made to compare the two methods, where real data were analyzed from public schools in Al-Khums – Libya, and this sample was chosen by the method of cluster random sampling by distributing forms the questionnaire was given to 199 male and female students with and without H. pylori infection, as well as some laboratory analysis was conducted for them. It was considered that the infected and uninfected children as a dependent variable, while the variables that were identified after reviewing some pediatricians were considered as independent variables. The overall classification ratio criterion was used as a criterion for comparison, and the study concluded that the proposed models gave identical results in terms of the significance of the effect and the importance of the independent variables included in the analysis, and that the logistic regression method gave a better classification rate than the discriminatory function.
