Statistics Sign Test Table. The sign test for a population median can be left tailed right tailed or two tailed. X is significant if it is less than or equalto the table value.
The null and alternative hypotheses for each type of test are as follows. Where x is the smaller number of and signs and n is the sample size. Statistical table 7 1critical one and two tailed values of x for a sign test where x the number of cases with the less frequent sign andn is the total number of positive and negative differences between pairs of scores i e ties are not counted.

For example if the probability value is less than the significance level at 05 null hypothesis will be rejected.
