What percentage of kids are right and what percentage are left handed?
Based on the distribution of pens in their class pack, Stabilo seems to work with the assumption that about eight out of 48 children (~17%) are left handed.
Statistics seem to indicate that the actual number of left handed people is lower, but exact numbers depend on which statistic you look at – and which country that statistic covers.
I wonder if the discrepancy in this class pack means that teachers using this pack usually have a few spare left handed pencils at the end of the year…
