In math classes solving statistical tasks by using procedures which the student learned by heart is usually used. The authors, thus encouraged learning and teaching statistics on the basis of realistic problems and problem situations, so that the student gets to know statistical concepts within the experience of resolving a real-life problem situation. With this approach to learning and teaching statistics, students acquired a better knowledge and were able to grasp, interpret and make critical evaluations of the statistical information, which was confirmed by the experiment that involved 269 first-grade high school students.
