Statistical analysis of testing results by section "Linear algebra and analytical geometry" in the Moodle environment

The article provides a mathematical and statistical analysis of the quality of the test in the section «Linear Algebra, Analytical Geometry» with the help of the following characteristics: reliability, validity, diskriminativnost. Testing was carried out in the environment of distance learning (LMS) Moodle. The problem statement: as a result, tasks that did not meet the specified requirements were rejected. The analysis of validity was carried out on the basis of checking the type of distribution of points. Testing the hypothesis of the normal distribution of test scores was carried out by Pearson's criterion. The reliability of the test was checked by regression analysis by splitting the test for even and odd jobs and determining the correlation coefficient between these groups. Further, the correlation coefficient was corrected by the Spearman-Brown formula and the significance of the obtained correlation coefficient was checked.
