Document Summary
Short film: accurate polls with a complete and unbiased reflection of a population, parameters: populations, sample: statistic. Statistic: a number calculated from a sample. Large sample then get a random sample of a smaller sample within that large sample. If variable is naturally continuous, should measure via an open-ended question: fixed-alternative questions. Limits the number of responses a participant can make. Choose responses that are appropriate for the questions. Can use nonverbal mode for describing preference (e. g. ) pictures for level of pain for kids.
