Re: 1994 WIMBLEDON ("FAST GRASS") vs. 2011 WIMBLEDON ("SLOW GRASS"): INTERESTING RESU
It's an interesting test but I think to get a better idea of how much court surface has changed at Wimbledon it would be better to compare a set of stats (i.e. 93-97) with a different set when the alleged "slowing" began (2005-2010). Don't get me wrong, the t-tests you applied are great, but I think a more complete picture could be calculated from comparing the "fast years" with the "slower years" rather than one year with another.
Trolling is defined by Herring as baiting and luring others into pointless and time-consuming discussions.
4 criteria of trolls:
1. Appearance of outward sincerity.
2. Posts designed to incite anger or "flames"
3. Posts designed to waste everybody's time with useless argument
4. Desperate desire for attention, any attention at all
Recognize them, don't engage and put 'em on your ignore list where they belong. Feed a troll and you're just encouraging their attention-seeking.
