Bronze coins

Coin catalogue section: Kelenderis
Coin corpus datasets: Kelenderis, bronze coins

Descriptive statistics are presented in Table 1. Types 7.1 and 7.2 are each represented by a single specimen weighing 1.00 g and 1.40 g, respectively. Figures 1–3 present box plots, relative frequency histogram of Type 7.3 (the bars represent the relative frequencies of observations in increments of 0.20 g) and cumulative distribution of Type 7.3, respectively. The weight of the only specimens of Types 7.1–2 are represented by green and red circles on the horizontal axis in Figures 2 and 3.

Type Count Mean Median Std. Dev. IQR
7.1 1 1.00 1.00
7.2 1 1.40 1.40
7.3 13 1.75 1.69 0.36 0.55

1The bottom and top of each box are the 25th and 75th percentiles of the dataset, respectively (the lower and upper quartiles). Thus, the height of the box corresponds to the interquartile range (IQR). The red line inside the box indicates the median. Whiskers (the dashed lines extending above and below the box) indicate variability outside the upper and lower quartiles. From above the upper quartile, a distance of 1.5 times the IQR is measured out and a whisker is drawn up to the largest observed data point from the dataset that falls within this distance. Similarly, a distance of 1.5 times the IQR is measured out below the lower quartile and a whisker is drawn down to the lowest observed data point from the dataset that falls within this distance. Observations beyond the whisker length are marked as outliers and are represented by small red circles.
