- jtbayly 2y agoThat may technically be correct, but it is incorrect in the real world. I submit that error is error in the real world. Mathematics can go jump off a cliff unless it wants to be helpful. :)
- roywiggins 2y agoZero average error conveys something important though: the error that there is, isn't biased positive or negative.
- pkilgore 2y agoThat's language failing us, not maths :-)
- noqc 2y agoWhat are you talking about? Error is a metric.
- jy14898 2y agoBy this logic, a broken 24 hour clock stuck at mid day has 0 error.
- Straw 2y agoThe average of its errors is 0- ie it is not biased. Ofc, the average absolute error, which in English one could very reasonably refer to as "average error" is much greater than 0.
