Abstract: Aspects of the disclosure provide methods and apparatuses for subjective evaluation. In some examples, processing circuitry receives scores graded by a subject to a media presentation. The scores by the subject includes a plurality of self comparison scores that are graded to self comparison tests in the media presentation. The processing circuitry applies a first rule and a second rule to the plurality of self comparison scores. The first rule requires a first subset of the plurality of self comparison scores in a first range.

The processing circuitry determines that the scores by the subject are qualified for the subjective evaluation in response to the first rule and the second rule being satisfied.
