Ask a psychic?

Perhaps show your real problem (not this vague handwaving) to a statistician?

If you are in a statistics course, talk to your instructor or teaching assistant?

This is R-help, not a statistics helpline, or a homework helpline. You are expected to know at least the basic statistics theory you need to implement, and provide a reproducible example using R syntax to get your helpers started in the right direction. 

Some points you should try to clarify: what do you mean by "average"? What distribution(s) does your data follow? What is your null hypothesis?

Hi

I have a table with four columns and 3 rows. I calculated the average for
each columns as average (A), average (B), average (C) and average (D), then
calculate the relative ratio as average (A)/average (B), and average
(C)/average (D). I would like to know how can I calculate the significance
between the two ratios.

Thanks,

Meng
