comparing multiple means between multiple groups

#1
Hi Everyone,

Pretty new to stats and want to make sure that I am running the right stats.

I have means (measured in months) from multiple sites. My supervisor asked me to determine whether there are any site specific significant differences in these means.

I am thinking that I should run a:

1. one-way ANOVA
2. Tukey's HSD.

Basically exactly what is done here given by this example: http://brownmath.com/stat/anova1.htm

Can someone please confirm that I am thinking of this correctly?

Also, if I wanted to use median instead of means could I use the same statiscal tests as outline above?

Thank you so much
