Fisher Sign Test
A robust nonparametric test which is an alternative to the Paired t-Test. This test makes the basic assumption thatthere is information only in the signs of the differences between paired observations, not in their sizes. Take the pairedobservations, calculate the differences, and count the number of 
s 
and 
s 
, where
is the sample size. Calculate the Binomial Coefficient
Then
gives the probability of getting exactly this many s and s if Positive and Negative values are equallylikely. Finally, to obtain the P-Value for the test, sum all the Coefficients that are 
and divide by
