This article explores the nature of the philosophy of Islamic education and its integration with the philosophy of mathematics in the learning process. The philosophy of Islamic education is rooted in the Qur’an and As-Sunnah and is further reinforced by the thoughts of Muslim philosophers. It encompasses three main aspects: ontology (the nature of existence), epistemology (the sources and methods of acquiring knowledge), and axiology (values and purposes). Islamic education aims not only to shape individual character but also to build a holistic educational system based on Islamic values. In this context, education is not merely a process of knowledge transfer but a means of fostering moral and spiritual development in learners. On the other hand, the philosophy of mathematics from the perspective of Islamic education emphasizes that mathematics is not solely an exact science of arithmetic, but also a discipline closely related to ethical and moral values in Islam. Mathematics is viewed as part of the divine order of Allah’s creation, reflecting His greatness. Therefore, the integration of Islamic educational philosophy and mathematical philosophy in learning offers a deeper approach to mathematical concepts. This approach not only enhances students’ cognitive understanding of the material but also instills spiritual awareness and values of faith and piety. By combining scientific and religious aspects, the learning process becomes more systematic, meaningful, and aligned with the comprehensive goals of Islamic education.

This study explores the application of the normal distribution in analyzing the height data of Mathematics Education students at FMIPA Universitas Negeri Medan in 2024. Employing a quantitative descriptive-analytic methodology, the research involved collecting primary data from 10 randomly selected students through a questionnaire-based survey. Descriptive statistical analysis revealed a mean height of 161.4 cm with a standard deviation of 8.79 cm. The median height was found to be 164 cm, while the mode was 150 cm, indicating a slightly skewed distribution. To assess the suitability of the normal distribution model, the Shapiro-Wilk test was applied, resulting in a W value of 0.921 and a p-value of 0.361, which exceeds the 0.05 significance level. This confirms that the sample data follow a normal distribution pattern. The findings were further supported through visual representation using histograms and analysis based on the empirical rule, which showed that approximately 68% of the students' heights fall within one standard deviation of the mean (152.81–169.99 cm). Additionally, probability calculations demonstrated that the likelihood of a student being 160 cm tall or shorter is approximately 43.64%. These results validate the effectiveness of the normal distribution as a tool for analyzing biological or physical characteristics, even in small sample sizes. However, the study acknowledges its limitation in terms of sample size and suggests that future research involve larger and more diverse populations to enhance generalizability. The study highlights the relevance of normal distribution in statistical modeling, particularly for educational and health-related data interpretation and decision-making processes.
