Example Sampling distribution of a statistic: gives (1) all the values that the statistic can take and (2) the probability of getting each value under the assumption that it resulted from chance alone Sampling distribution of the mean: gives all the values that the mean can take and the probability of getting each value if sampling is done at random from a population where the independent variable has no effect (H is true)...
