@Jay The correlation of rank achieved in a certain week to overall rank (for some kind of sports competition @hobodave gave me the data for)
It means that if somebody does well in Week 5, it is probable that they will do well overall too. Week 3, not so much. (Assuming that this happens all the time in the same way, for real confirmation the data for many years should be studied, not the data for one year only)
Using the default method (the one Excel uses) assumes that the ranks have meaning like integers - so that the person at rank 4 is exactly twice as bad as the person at rank 2, and the person at 40 is exactly 10 times as bad as the one at 4
I would suggest instead, tagging questions that are specifically targeted at a group with an appropriate tag. "Is it possible to make vegan omlets?" would certainly support a vegan tag
specifically targeted at a group with an appropriate tag
There's a difference between being coincidentally "targeted" at a group and specifically tagging something to "target" a group. You're doing the latter @mfg.
You're trying to use the tag as a notification of sorts. Maybe someone can come up with a better counterpoint, but let me try: I know molecular gastronomists probably have a high level of knowledge regarding the Maillard reaction, and I have a question about searing a steak. This would never get tagged molecular-gastronomy just because I want them to see it.
It is even slightly discriminating to tag questions in a way which connects a subject matter with a defined group. I can imagine what would happen if I tagged a question about picking strawberries with Mexican, on the assumption that Mexicans know most about it.
