A Kruskal-Wallis test is a non-parametric test used to compare three or more independent samples. The test statistic is denoted as H and its value represents the degree of difference between the medians of the samples. The p-value is then calculated to determine the significance of the results. In this case, the p-value is 0.025, which means that there is a 2.5% chance of observing these results by chance alone. Therefore, we reject the null hypothesis and conclude that there is a significant difference between the groups.
