What is in this set

The numbers in this set run from 2 to 20.
Every problem in it will have an even number of values, so the median is a midpoint.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 93% of the problems: the middle of the list as written was taken; the numbers have to be put in order first.
Answers are a decimal.

Drawing 240 problems from this page produced 238 different ones, 99% — so a sheet of 20 is a new sheet almost every time.

The same skill, harder or easier

We would put this in front of a grade 6 class. That is our judgement, not a standard, and it is printed here so you can disagree with it. Everything else we put in that year.
