So, assuming all typos inserted are in fact a serious error to the program and assume that the output they used to compare is a unit test. Then an interesting number to look at is: Errors remaining = Successful run - Faults caught in unit test In that regard most languages in the study are quite equal. Although with the static languages you most likely catch the errors much earlier and you probably get a much better hint of where the error is, instead of just an assertion that you have an error. And of course this assumes that you do have unit tests.
