K population medians are equal. If the minimum sample size requirements cannot be met, you should use a nonparametric equivalent to the parametric hypothesis test (i.e. Online calculators with steps (free):

If n is the total sample size, k is the number of comparison groups, r j is the sum of the ranks in the jth group and n j is the sample size in the jth group, then the test.

The sample size goes up as the square of the standard deviation of the data (the variance) and goes down inversely as the square of the effect size. Non parametric means that the test doesn't assume your data comes from a particular distribution. Sigmaxl > statistical tools > nonparametric tests). The larger the effect size, the stronger the relationship between two variables.
