Her experiment couldnt function properly because there is no accuracy to the test since both groups perform well, this is known as a ceiling effect
The term ceiling effect is a measurement limitation that occurs when the highest possible score or close to the highest score on a test or measurement instrument is reached, thereby decreasing the likelihood that the testing instrument has accurately measured the intended group.
