Spearman’s rank correlation test

Rank from testing under Duhring Chambers using 25% shampoo solutions. Spearman s rank correlation test provides a correlation coefficient of 1.0 and a Z value of 2.0, indicating a significant relationship between in vivo irritation and calculated ranks. 

No clear relationship exists between taxonomic diversity and disparity (Spearman s Rank Correlation Test), no matter which disparity metric is applied the number of species in a given area does not predict the level of disparity. This anphasises the need for both diversity and disparity metrics to be explored when studying biogeography. Comparisons between diversity and disparity in the case of the cuttlefishes reveal various patterns. The most striking cases are... 

Spearman s ranked correlation tests were conducted on the data sets to compare the various sampling and analysis techniques (Spearman s ranked correlation coefficient = p). A significance level of p<0.05 was used throughout the study.
