In a statistics class an instructor had just delivered what he thought was a very scintillating presentation on two-variable regression analysis. He looked up from the glare of the overhead projector and noticed that a student in the back of the classroom was in a semi-snooze. This proved too much for the instructor's ego and he scowled angrily at the student. He said," Young man I want you to answer a question about this problem. For a person with an X-value of 45, is the predicted Y-value above or below the subgroup Y-mean?"
The dazed student looked up for ten seconds then responded,"Yes."
The instructor could not believe his ears and quickly snapped back, "Young man this is not a yes-no question! Just say above or below."
The student responded, "Above or below!"
The instructor answered, "Yes."
The student was wide awake now and retorted, "SIR, THAT WAS MY ORIGINAL ANSWER."
*Thanks to my colleague and good friend Elmer Lemke for reminding me of this answer he once got on a comprehensive examination. Of course, I took the liberty to augment and embellish this story.
