Description

AnovaRanks

Demonstration from Statistics with 15 cases, 3 attributes. Useful for Demonstration

Demonstrates how to perform a Kreskas-Wallis one-way analysis of variance by ranks (the nonparametric analog of the Analysis of Variance test).

RankCorrelationBrief

Demonstration from Statistics with 50 cases, 2 attributes. Useful for Demonstration

Shows how to do a test of the significance of rank correlation. This test is especially useful when, as is true for this data the relationship between x and y does not appear linear.

RankCorrelationExample

Demonstration from Statistics with 9 cases, 5 attributes. Useful for Demonstration

Illustrates how to show the workings of a Rank Correlation test with Fathom.

SumRanks

Demonstration from Statistics with 10 cases, 3 attributes. Useful for Demonstration

Demonstrates how to perform a rank sum test for two independent samples (sometimes called the Mann-Whitney U Test, which is the nonparametric analog of the Compare Means test).
