不是阿。赫赫

hehe. i see .

you might have panel data.

are you using spss? I guess stata might have some useful function. Can not recall the details. I need to go back and check.

if you want to use post hoc in three+ group comparison, stata can do this with ANOVA.

not quite sure about other statistics softwares.
