The qualitative method plays a significant role in educational psychology. When it comes to analysis of tests a perfect example is an aptitude test. Aptitude test refers to the test that shows the person's potential. For example, you are going to test a student if they have a potential to be part of a special science program. With an aptitude test, you can learn if the student is qualified or not. In this example this benefits the students and the teachers. However, the aptitude test may have biases such as linguistic biases. If the student is more immersed in the language of the specific test, that student will gain more advantage.
