The sign test relies on the fact that, if the true population (of differences) median is equal to zero, there is a 0.50 probability of obtaining a positive difference. Thus, this is a binomial experiment and a difference will be either positive or negative (ties are ignored). When the number of observations (non-zero differences) is at least ten, the normal approximation may be used.
