A very simple thing; I have to collect data with 4 different group size. Something like;(adsbygoogle = window.adsbygoogle || []).push({});

Group A; 12.4, 17.8, 12.5 ...

Group B; 15.2, 9.5, ...

I simply want to know if the differences between the groups are statistically signifiant. I don't want anybody to explain the me the math, I just want the name of the statistical test.
