'Average' and 'Mean'
The text says, 'Vocabulary lists in the medieval texts ranged from 52 signs to 472, with "the average at 178 and a mean at 145."'

I appreciate it's a referenced quote from elsewhere but it's statistical nonsense: 'average' and 'mean' mean the same thing so can't have two different values.
