cuz they felt like putting it on there.
Rho is the seventeenth letter of the Greek alphabet.
If what you're after is a simple solution in a statistical software, the quick answer is no. If your data dictates the use of nonparametric statistics (so you cannot use Pearson's), it may be an idea to try logistic regression instead.If, however, you're up for a challenge, there has been a recent (2010) paper exploring the possibility of using Kendall's tau, Spearman's rho and Spearman's footrule in multivariate analysis:Journal of Multivariate AnalysisVolume 101, Issue 10, November 2010, Pages 2398-2410Concordance measures for multivariate non-continuous random vectors by Mesfioui M and Quessy J-F.doi:10.1016/j.jmva.2010.06.011Good luck!
Although Spearman's rank correlation coefficient puts a numerical value between the linear association between two variables, it can only be used for data that has not been grouped.
m, m+6, m+12
That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/2
Spearman's rank correlation coefficient is given in the related link at the bottom of this page.
spearman's rho
The Spearman coefficient can be calculatated only for two characteristics of the observed population, as for kendall's W there may be two or more characteristics.
not otherwise....split half method is one way of determining reliability of your test and Spearman-Brown formula is a technique used to re-calculate the correlation of your test when you split your test items into half.... this means that the result of Spearman-Brown provides you the correlation of your test in full length.
