Okay, two posts above does have the correct dataset (which was the original dataset). I was confused for a moment whether the median in a quartile included the two averaged numbers when total row count is even. It does. In the case of the values 1 through 10 the median would be 5.5, and the quartiles would be the median of everything above 5.5 (6, 7, 8, 9, 10) and below 5.5 (5, 4, 3, 2, 1). So the upper quartile would be 8 and the lower quartile would be 3.

Sorry for the momentary confusion!
