A nonparametric method for determining the differences between two populations based on two matched samples where only preference data is required is the
1. Mann-Whitney-Wilcoxon test
2. Wilcoxon signed-rank test
3. sign test

When ranking combined data in a Wilcoxon signed rank test, the data that receives a rank of 1 is the
1. lowest value
2. highest value
3. middle value
4. This can vary according to data
The collection of statistical methods that require assumptions about the population is known as
