I have two groups A and B, each of which consists of 5 samples. Each sample is described in a vector of length (>1000) of continuous numeric values (characteristics). I want to test if the sample in the first group varies between each other more than the sample in the second group.
I tried one-way ANOVA for each group independently and calculated the F-test statistic for each group. Now, can I compare the two obtained statistics directly (so if statistic 1 > statistic 2 I say the first group has more variance between its samples than the second group)? or do I need to perform statistical significance to compare the two statistics?
