Draw on your experience to determine sample size: conventional: See what the sample size has been for similar studies. The frequency distribution of all the elements of a population: sampling distribution: The frequency distribution of all the elements of an individual sample. The probability that a particular interval will include the true population value; also called the confidence coefficient: confidence interval: The interval that, at the specified confidence level, includes the true population value.
