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.
