Boxplot of the distributions of the osteon chemistry of two archaeological but non-interred individuals, the Apostle/KLR-11251 and Maiori/KLR-11742, expressed as µg/g for each element. The p-values at the top of the diagram are Dunn’s multiple comparison tests with alpha = 0.05 calculated after the one-way ANOVA analysis. The boxes indicate the extent between Q1 and Q3; the error bars indicate limits of Q1 + 1.5*IQR; the red crosses are the means; lines inside boxes are the medians; open circles are outliers in the range 1.5*IQR and 3 standard deviations; closed circles are outliers over 3 standard deviations from the mean; and crosses are extreme outliers according to the 3*IQR rule
