cop out math guys use at their convenience usually to try and win an argument on an online gambling forum.

"it was too small of a sample size to determine a definitive answer" or "you need a larger sample size to determine a definitive answer", whichever suits their postion at the time.

Small Sample Size 

Used in statistics when there is not enough data to make a conclusion. It has two major uses:
1. In statistics, more specifically baseball statistics/sabermetrics
2. On Myspace and Facebook, when the profile picture of a private account does not determine whether the person is attractive or not.

1. Person 1: Jeff Francoeur is a good hitter! Look at what he did in 2005!
Person 2: Those 70 games are a small sample size! He's been a below-average hitter since then.
2. Random Girl: Here's my myspace, myspace.com/amisexyoraminotyoucanttellbymyprofilepic
Person 1: I'm calling small sample size on that profile pic.
Person 2: You need to friend us so we can make a statistical conclusion. :)
