<translate> Kwa mfano, Katika hali ambayo hatujui jinsi teknolojia ilivyojaribiwa - lakini bidhaa inarekodi usahihi wa 98, haijulikani iwapo usahihi ni kuwaweka wavamizi nje ya jukwaa au usahihi upo kwenye utambulisho sahihi wa watumiaji. Kuna maelewano kati ya haya mawili, na makosa katika matukio yote mawili huleta athari, na uwezekano wa kujitokeza kwa upendeleo. <eng>
For instance, In a case where we dont know how the technology was tested - but the product records a 98 accuracy, its not clear whether the accuracy is in keeping intruders off the platform or the accuracy is in proper identification of users. Theres a trade-off between the two, and errors in both cases carry consequences, with a potential likelihood of bias occurring in either.
