問題文
Two validation runs on the same model and the same data produced different performance figures. What should the practitioner establish first?
選択肢
- Whether the two runs were performed by the same person using the same environment since a difference in either would account for the variation between them.
- Whether the difference between the two figures is large enough to change the approval decision since a small difference would not affect the conclusion and would not therefore justify the effort of investigating the cause.
- Which of the two figures is correct so that the approval decision can proceed on the basis of the accurate one and the incorrect run can be discarded from the record without delaying the assessment any further.
- Which steps in the process are not fully specified since a repeatable process gives the same result.
