Stat > Nonparametrics > 1-Sample Sign

You can perform a 1-sample sign test of the median or calculate the corresponding point estimate and confidence interval. For the one-sample sign test, the hypotheses are

H0: median = hypothesized median versus H1: median ≠ hypothesized median

Use the sign test as a nonparametric alternative to 1-sample Z-tests and to 1-sample t-tests , which use the mean rather than the median.

Dialog box items

Variables: Select the column(s) containing the variable(s) you want to test.

Confidence interval: Choose to calculate a sign confidence interval.

Level: Enter a confidence level between 0 and 100 (default is 95.0).

Test median: Choose to perform a sign-test, then specify the null hypothesis test value.

Alternative: Click the arrow to choose the kind of test performed by selecting less than (lower-tailed), not equal (two-tailed), or greater than (upper-tailed) from the drop-down box.
