WebMay 27, 2014 · Yes, n-1 is the degrees of freedom in that example. Given a t-value and a degrees of freedom, you can use the "survival function" sf of scipy.stats.t (aka the complementary CDF) to compute the one-sided p-value. The first argument is the T value, and the second is the degrees of freedom. WebHowever, the p-value is equal to two times the p-value for the upper-tailed p-value if the value of the test statistic from your sample is positive. Example of calculating a lower-tailed p-value Suppose you do a one-sample lower-tailed z test and the resulting value of the statistic calculated from the data is −1.785 (ts= −1.785). glen helen amphitheater live nation
