Hi everyone,

I need some help. Does anyone know whether the Mood’s median test [Stata command ‘median’, I guess?] is still used by people? I read from Wiki that the Moods test is ‘obsolete.’ Is it true?

If it is true, should I use the Mann–Whitney test instead [Stata command 'ranksum']?

And which approach is more suitable for my task, as outlined below:

My task is to test the differences in the median annual expenditure on some consumer products. The sample size is about 1000 [about 250 per year for 4 years]. I want to test the difference in the medians between income groups [one group vs the rest of the groups combined], and also to test any changes in the medians from one year to the next year for each income group.

I would appreciate any expert comments.

Thanks!
