The stochastic model of the impact of context factors to educational results of Tomsk school graduates

The article describes the factor model of Tomsk region schools functioning which was developed and investigated using the STATISTICA system. The constructed model describes an impact of different variables (context factors) on educational results of Tomsk school graduates. At the preliminary stage the most significant variables were determined, the exploratory data analysis was made using the method of principal components. There were formulated 3- and 4-factor models using Kaiser-Guttman's and Cattell's Criteria. Factor rotation with Varimax method allowed to interpret factor loadings clearly. In this work there were investigated the quality of the factor model for different types of schools such as urban, country, ungraded ones.
