I have the following table,
I used chi square test of independence to find whether the frequencies of 'c.388A>G' are same across SAMPLE_A, SAMPLE_B and SAMPLE_C. And the p-value from the test shows that they are not the same. Now , I want to make a statement that "The frequency of c.388A>G was significantly higher in SAMPLE_C compared to other groups that had similar but lower frequency." But to say that, should I do any other test? If yes, can you please advise what test I should do?
