From: Dissecting complex transcriptional responses using pathway-level scores based on prior information

First Feature Second Feature (Non)-Parametric? APPROPRIATE TEST
categorical categorical non-parametric hypergeometric
quantitative quantitative parametric Pearson
quantitative quantitative non-parametric Spearman, Kendall
categorical quantitative parametric two-sample t-test
categorical quantitative non-parametric Wilcoxon-Mann-Whitney, Kolmogorov-Smirnov
  1. When analyzing the statistical association between two features across the genome, the choice of statistical test depends on whether the features are categorical or quantitative, and whether or not a parametric method can be used. For each case the appropriate test is listed.
