A researcher plans to evaluate a new reading program by measuring students’ reading skill before and after the program begins. If all the students have high reading skills scores before the program begins, then the measurement procedure has a sensitivity problem known as a "ceiling effect".

Explanation:

The effect which happen if a large proportion of topics on the observed variable have the maximum scores in a study is understood as "ceiling effect". This allows segregation impossible between subjects at the top end of the scale. Exam paper, for instance, will result in 50 percent of students scoring 100 percent. The restriction of calculation happens when the highest score achievable or near to the highest score on a test or measuring device is reached, thus reducing the risk that the test device has correctly calculated the expected domain.
