Figure 8. The box plot illustrates the students’ scores on the questionnaires addressing the underlying theory of the project. Identical questions were asked before (blue) and after the laboratory session (orange). Median values are indicated by a horizontal line and are 7 for the pre-laboratory and 11 for the post-laboratory questions. Whiskers represent the minimum and maximum observed values, while colored boxes encompass the interquartile range (first to third quartile)
