Hi everybody,

I'm currently trying to perform Kruskal Wallis test comparing 3 groups with unequal sample size. Does anyone know if it's feasible?

In an attempt to solve the problem I tried to replace the zeros with NaN but it gives me the same results as with zeros.

Function used:

[p,tbl,stats] = kruskalwallis(x);

Best,

Eric

This can be done using the grouping variable option in the kruskalwallis function. See the grouping example in the function's documentation here: Kruskal Wallis - Grouping Example
