Hello,

I am using t-test to check if the difference between two poulations is
significant. I have a large N=20,000, 10,000 in each population. I compare a
few different poulations with eachother and though I get different t-scores,
I get the same  p-value of 10^-16 which seems like the limit for this
function. Is this true and is so, is there a workarounf to get a more
sensitive/accurate p-value?

Thanks
