WebThe sampling distribution is the distribution of a statistic i.e., a data summary such as the sample mean whose value changes from sample to sample. In hypothesis testing, a test statistic compares the data to what is expected under the null hypothesis, and is defined in such a way that its value is larger under the alternative hypothesis.
