Cheat metrics in the exam room

Shows Mr. Bean cheating.

This post highlights what cheat metrics are, and how they can help contract cheating (homework outsourcing) detection, by tying the concept down to the real-world. It is often misunderstood that cheat metrics is a technical concept, hopefully, this concept will convince you otherwise.

Imagine yourself, working as an exam proctor. You see the following three behaviors in an exam room, which among these three students would you confront about cheating?

Whatever your answer is, don’t tell me. Instead focus on the attributes which led you to your answer.

You just screened the students based on behavioral data You saw Mr.Bean’s neck turned towards the direction of the other test-taker’s sheet and the intense focus on his face. Similarly, the note passed between the two girls (the way their hands interact) seems like a sign that something is up.

The behavioral attributes you just looked at, these attributes are kind of like cheat metrics. They depict abnormal behavior regards to the situation. Doctupus does what you did right now as a proctor: screen for instances of abnormal behavior and report it.

As contract cheating is, well, a behavior, it is only adequate that we look for behavioral data to detect contract cheating.
