Tukey or Turkey...

You are probably like what the?? That's my exact reaction when I see these words. I'm talking about stats here. Tukey (pronounced 'too''key' - which reminds me of 'turkey') is some method you use to control the family-wise for inferences on all comparisons. Yeah what's that suppose to mean? I have no idea but had better work that out by tomorrow which is when I have an exam on a VERY CLUELESS subject...wish me luck!
