What is the ceiling effect of the ceiling
The ceiling effect is also known as the high limit effect: when the task is required to complete the task is too easy, all the different levels (quantity) of the independent variables have achieved very good results, and there is no difference between the situation, we said that the experiment appeared high Limit effect. [Example 1] The teacher in order to test the level of student learning, and out of a paper, if the paper is too simple, the result is generally achieved a high score students. And thus can not be tested from the scores of students learning level. Then this phenomenon is called "ceiling effect". So how to avoid it? The usual method is to try to avoid the extreme reaction by experimenting with the experiment, and then try to examine their response to the task by testing a small number of pre-subjects. If the reaction of the test is close to the top or bottom of the target range, the experimental task needs to be corrected.
Ceiling effect, floor effect that is high or low limit effect. For example: the subject is too easy to test, resulting in most of the individual scores generally higher phenomenon, known as the ceiling effect. Quiz questions too difficult, resulting in most of the individual scores generally low phenomenon, known as the floor effect. We often come to you and hope that you can help
Both refer to some extreme reaction of the dependent variable. The ceiling effect refers to almost all of the dependent variables showing a high score or a high level; the floor effect is that the dependent variable almost always exhibits a low score or a low level. When this happens, to avoid the direct result of the extreme results attributed to the operation of independent variables, to carefully check the relationship between the task attributes and subjects, such as whether the task is too simple or too much of the subjects and so on
