Fight duration. Boxplots of the duration (in seconds) for each type of fight. Boxes span the range from the first to the third quartile and the thicker line inside represents the median. Whiskers below and above the boxes show the minimum observation above the lower fence (Q1 − 1.5 IQR) and the maximum observation below the upper fence (Q3 + 1.5 IQR). Outliers are represented as solid circles. Data of individual fights are visible as dots. The red horizontal lines represent duration means and the red vertical lines represent standard deviations relative to the means. Asterisks show the significance of the differences based on the Linear Mixed Model and the Welch two-sample t-test
