Analysed coins
| Coin catalogue section: | Holmoi |
| Coin corpus datasets: | Holmoi, Group 2 |
The numbers of analysed coins are given in Table 1. Coins whose weight is unknown or unreliable, or that are excessively corroded or damaged, are excluded from the analysis.

Analysis
Box plots1 and basic descriptive statistics for bronze units (Type 2.5) and half units (Type 2.6) are presented in Figure 1 and Table 2, respectively. Type 2.6 is represented by a single specimen weighing 0.77 g.

Table 2: Descriptive statistics of bronze types
Figure 2 presents the relative frequency histogram of Type 2.5. The bars represent the relative frequencies of weights from 0.70 to 1.90 g in increments of 0.10 g, while the weight of the only known specimen of Type 2.6 is represented by the red circle on the horizontal axis. The cumulative distribution of Type 2.5 is shown in Figure 3, where the weight of the single specimen of Type 2.6 is again represented by the red circle on the horizontal axis.

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. Above the upper quartile, a distance of 1.5 times the IQR is measured, and a whisker is drawn up to the largest observed data point in the dataset that falls within this distance. Similarly, below the lower quartile, a distance of 1.5 times the IQR is measured, and a whisker is drawn down to the smallest observed data point in the dataset that falls within this distance. Observations beyond the whisker length are marked as outliers and are represented by small red circles.
