Significance of Kruskal Wallis test
The Kruskal-Wallis test is a non-parametric statistical test that evaluates whether there are significant differences among three or more independent groups. It is particularly useful for analyzing data that does not follow a normal distribution. The test assesses the medians of the groups to determine if they originate from the same distribution, often applied in various studies, including those examining insomnia scores and antimicrobial effects. A significance level of P ≤ 0.05 is typically used in such analyses.
