Questionnaire results

This page shows boxplot visualizations comparing the responses to the different statements from the questionnaires regarding the navigation techniques, in the same order as given on the questionnaires.
The central thick line shows the median, the cross is the arithmetic mean of the answers on a scale of 1 to 5. The lower and upper borders of the colored boxes display the positions of the first and third quartile, while the whiskers show the minimum and maximum values. Outliers (displayed as circles) were determined as values outside of the 1.5-fold interquartile range.
The actual questions asked are listed at the bottom of the page.
