Hi,

I have the outcome variable in a research project as
the waiting time, which is a continuos variable.
However it is a skewed distribution and therefore I
would like to use the medians instead of means. If I
want to compare the median waiting time between
different subgroups, for example male vs. female, or
low income vs. medium income vs. high income, how do I
go about doing that?
To my understanding the t-test or anova looks only for
differences in the means. In case of a skewed
distribution, is it appropriate to use them for this
purpose?

Thanks.
Ashwin
