In this study a tractographic analysis of the cingulm in Autism Spectrum Disorders was performed. Characteristic measures of the cingulum reconstructed from DTI data of ASDs and controls were analyzed by the techniques of exploratory data analysis (EDA). The Wilcoxon test revealed a significant increase in the length of streamlines bilaterally in ASD group than in controls. The methods of EDA revealed that the length measures followed a log-normal probability distribution. The use of probability distribution allow to increase the robustness of statistics, to find outliers and to provide a basis for further data collection experiments.
