Quizplus · Accepted Answer

A floor effect occurs when a test is too difficult for most participants, resulting in scores being clustered at the lower end of the distribution. This is the opposite of a ceiling effect, which occurs when a test is too easy for most participants, resulting in scores being clustered at the upper end of the distribution. The Yerkes-Dotson Law refers to the relationship between arousal and performance, and the degree of response effect refers to the phenomenon of participants providing responses that reflect their level of knowledge or understanding rather than the accuracy of the stimulus presented.
