This may seem weird, but is this being posted because of some standardized testing?

My 6th grader took home a practice standardized test today. Last question on the test required a MAD computation.

He didn't know what MAD was and I had to look it up myself.

I think understanding the idea behind MAD is great and potentially useful and interesting.

However, I'm not sure what 6th graders are going to be able to grind through two iterations over a data set to get the correct answer.
