Statistical Techniques

The analysis conducted in this paper makes use of several standard statistical tests. These are the Wilcoxon matched-pairs rank-sum test, the proportion test, the matched-pairs t-test, Spearman's rank correlation test and the rank correlation test for agreement in multiple judgements. For the benefit of readers who are unfamiliar with these tests, we briefly summarise them here. This appendix was constructed using Gopal K. Kanji's 100 Statistical Tests kanji.
