This scenario exemplifies construct-irrelevant variance, where factors unrelated to the construct being measured (in this case, knowledge or mastery of the test content) adversely affect the test performance. The student's lack of sleep, leading to exhaustion, is an external factor that impacts her ability to demonstrate her knowledge, thus introducing variance that is irrelevant to the construct (knowledge or skill) the test aims to measure.
