Obtaining the P values for the t stat

I have both the tstat and the degrees of freedom, is there a quick way to find the P value of a two tailed hypothesis at a significance of 0.05

Answer 1

[dpb]

p = 1-tcdf(t,n-1) % Probability of larger t-statistic

requires Statistics Toolbox...

[Jamol Bahromov]

Shouldn't p multiplied by two for a two-tailed p-value?

[O.Hubert]

It should be noted that t should be positive to obtain sensible results and yes, p should be multiplied by 2 to get a two-tailed test.

To have t positive, replace it by abs(t).
