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.
We address this question by calculating the. value of a test statistic, i.e., a particular real-valued function of the data. To decide whether. the value of the test statistic is consistent with the null hypothesis, we need to know what. sampling variability to expect in our test statistic if the null hypothesis is true. In other. words, we need to know the null distribution, the distribution of the test statistic when the.
