M – arithmetic mean (average value of obtained scores); Mdn – median (middle value of obtained scores); Min – minimum average value of obtained scores; Max – maximum average value of obtained scores; 25% – 75% – interquartile (the range in which there are 50% of central results); MaxD – value of the expected result frequency; K-S – significance of differences between the observed and expected (MaxD) result frequency; nd – *the distribution of results differs significantly from the normal distribution
