Two-Related-Samples Tests
The Two-Related-Samples Tests procedure compares the distributions of two variables.
Example. In general, do families receive the asking price when they sell their homes? By applying the Wilcoxon signed-rank test to data for 10 homes, you might learn that seven families receive less than the asking price, one family receives more than the asking price, and two families receive the asking price.
Statistics. Mean, standard deviation, minimum, maximum, number of nonmissing cases, and quartiles. Tests: Wilcoxon signed-rank, sign, McNemar. If the Exact Tests option is installed (available only on Windows operating systems), the marginal homogeneity test is also available.
Two-Related-Samples Tests Data Considerations
Data. Use numeric variables that can be ordered.
Assumptions. Although no particular distributions are assumed for the two variables, the population distribution of the paired differences is assumed to be symmetric.
To Obtain Two-Related-Samples Tests
