    Can someone explain to me what the 2* signifies in Exact Sig. [2*(1-tailed Sig.)]?

    While I rely on the Asymptotic Significance above the Exact Sig., I am still quite curious. It also seems odd that the Exact Sig. 1-tailed is sometimes larger than the 2-tailed value when it should be roughly half the value of a 2-tailed test.
