Quizplus · Accepted Answer

The term "ceiling effect" refers to a situation where a measurement tool or test is limited in its ability to capture a true range of scores because the majority of participants achieve the highest possible score. In this scenario, the fact that all participants received maximum scores suggests that the noise level did not have an effect on reading comprehension, or that the measurement tool was not sensitive enough to pick up any variations in performance. This is an example of a ceiling effect.
