[Corpora-List] Which math.statistics criteria t-test or chi-squared?

[Michele Filannino]

Dear Yuri,

it strictly depends by:

   - the number of samples (more than 30?)
   - the number of factors (2 or more?)
   - are the data from each factor becoming from the same samples?
   (dependent vs. independent factors)

Let me know, I will tell you which one is better to use. ;)

Bye,
Michele Filannino.
