問題文
An education platform's essay scoring assistant has 89 percent agreement with human graders overall. Agreement is 91 percent for one learner group and 84 percent for another. Improving the lower group's agreement to 90 percent would reduce the higher group's to 89 percent, leaving the overall figure roughly unchanged. What should the architect recommend?
選択肢
- Make the change only after confirming that the 7-point difference is caused by the model rather than by the human graders.
- Make the change, since a system used for academic assessment should not perform meaningfully worse for one learner group, and the overall figure is preserved.
- Do not make the change, since the overall figure does not improve and effort should go to raising it.
- Do not make the change, since it reduces performance for a group that is currently well served.
