The Kruskal-Wallis Test

  • Kruskal-Wallis Test assumes that each of our samples is an independent SRS and will give trustworthy conclusions only if this condition is met.

  • Kruskal-Wallis Test assumes that your data come from a continuous distribution.

  • Kruskal-Wallis Test is an alternative to One-Way ANOVA when the guidelines for its use are not met (such as when the largest sample standard deviation is more than twice as large as the smallest).
