An answer, by analogy- If you yell into a microphone, the recording will come out distorted and inaccurate. Yet if you speak normally into one, the recording will sound rather true to life. This is because the microphone has been tuned to a certain level of sensitivity, and when that threshold is exceeded, what it records is clipped. A similar principle holds for many types of human tests in education, psych, etc. |
