The most difficult for the participants was the fifth task, whereas the lowest number of errors is made in the third task, which shows the student’s knowledge of the conceptual and categorical apparatus of statistics and their interest in the task content and form.

At the same time, high variation of points earned by the participants (69 points), the coefficient of oscillation (174 . 5%) and the quadratic coefficient of variation (40 . 6%) showed high variation and unreliability of the average.
