# P values with the t-distribution watch

1. Hello,
I've been confused on this topic for a while and i'm not understanding how to calculate the p-value for a t-test statistic for the 1-tail tests and 2-tail tests via the tables. Could someone please help explain to me on how this is done with an example perhaps?
Thanks!

I suspect that you may be getting confused by the tables that you are using - but since I can't see those, I can't tell. The bottom line is that the the t-distribution is symmetric about its mean, and looks like a distorted normal distribution. Hence you use it in the same way, for one and two sided tests, that you use the normal distribution
