1 The P-value is the probability of observing a sample statistic as extreme as the test statistic. 2  Since the test statistic is a t-score, use the t Distribution Calculator to assess the probability associated with the t-score, given the degrees of freedom computed above.
The P-value provides a measure of this distance. The P-value (in this situation) is the probability to the right of our test statistic calculated using the null distribution. The further out the test statistic is in the tail, the smaller the P-value, and the stronger the evidence against the null hypothesis in favor of the alternative.
