Abstract
This research demonstrates the use of some statistical tests popular in Data Science applied in Social Sciences. The usage is shown on the case of investigation of what factors might affect students’ performance. Most recent studies focus mostly on short-term results such as performance in high school. This paper examines these factors in the long-term run, taking the factors in schools that might affect a person in the future university. Analytical approach is used to derive most significant factors. The results approve and disapprove some stereotypes that were present before the research. The derived factors give motivation for further investigation of educational success.
