Figure 2
THe boxplot titled “t-stat”. The horizontal axis is labeled “t-stat” and ranges from negative 20 to 25 in increments of 5 units. The vertical axis displays values from 1 to 38 in increments of 1. Each numbered row contains a horizontal boxplot with whiskers and individual plotted points. Two vertical reference lines appear at approximately negative 2 and 2. Most boxplots cluster around zero, with many interquartile ranges falling between approximately negative 3 and 3. Several whiskers extend between 5 and 10 on the positive side, with the longest visible positive whisker reaching approximately 9 to 10. On the negative side, one whisker extends close to negative 20, representing the longest negative spread. Individual plotted points beyond the whiskers appear near approximately negative 5, around 9 to 11, and near 23 to 24 on the positive side. The majority of distributions remain concentrated between negative 5 and 5. Note: All numerical values are approximated.BOX PLOT to display distribution of the dataset. Source: Authors’ estimation
