Technological improvement rates of digital and non-digital technologies. Notes: The boxplot shows the distribution of improvement rates of 1753 different technologies from Singh et al. (2021). The split into the digital or non-digital group is based on the approach proposed by Inaba and Squicciarini (2017). The horizontal line shows the median, the big dot the mean, the upper limit of the box the 25th, and the lower limit the 75th percentile. The length of the whisker shows the data that are within 1.5 times the interquartile range. Outliers are marked by small dots
