1. YOU falsely claim that "all" students who buy papers use them to cheat;
I posted that opinion almost two years ago and at the resolution of that matter (almost two years ago) I had already conceded to changing my position to "most" instead of "all."
2. YOU falsely claim that my position is that "no" students who buy papers use them to cheat;
No, I did not.
3. YOU falsely claim that no sample data and personal assumptions are better than concrete, limited data.
The evidence of students complaining on this message board about not getting the grade they want from the papers they bought is more than enough to topple your 7/8-based inference.
But if you want to get technical with it, poor evidence
is just as bad or even worse than no evidence where the application of statistics is concerned.
Attend any basic seminar or 101 class on statistics and you'll hear the same thing. Poor evidence can lead decision makers to make wrong inferences which may have disastrous outcomes. However, this is not the case for this scenario that we have. There is OVERWHELMING evidence of students submitting papers for credit based on the posts of students on this message board alone.
Also, I think that nobody in his/her right mind would side with your implied claim that most students use the papers that they purchase "properly."
