FTEST
 "Summary: Returns the result of an F test (the probability that two datasets
have come from the same total population)"
Excel says it tests the probability that the variances are not
significantly different (which is not the same as coming from the same total
population).
[ed:] TODO: who can provide insight?
 "An Ftest returns the onetailed probability" Excel currently describes
this as the 2tailed probability. I believe that is correct (see
http://www.coventry.ac.uk/ec/~nhunt/pottel.pdf). Old versions of Excel eg 97
describe it as one tailed. It would be worth someone with real knowledge
checking this out.
