Hair thickness differences. Boxplot for the hair thickness measured by SEM on ~80 samples for each eruption type specimen. The central red line indicates the median, and the bottom and top edges of the box indicate the 25th and 75th percentiles, respectively. Triangular markers display the confidence interval around the median. The whiskers extend to the most extreme data points not considered outliers. KI samples are the thickest, HMM the thinnest. LOEs values place in between the previous two. The notch (triangular markers) do not overlap, indicating that the distribution medians strongly differ. Median values are: 233, 158 and 62 µm respectively for KI, LOE and HMM samples.
