Student Exploration: Populations and Samples (ANSWER KEY) Download Student Exploration: Populations and Samples Vocabulary: frequency distribution, normal distribution, population, sample ) 1. How would you describe the shape of this distribution? Prior Knowledge Questions (Do these BEFORE using the Gizmo.) A frequency distribution indicates how many data points have each value or range of values. Suppose a large number of people were quizzed on how many U.S. state capitals they can name. The histogram to the right shows the frequency distribution of their results, with no studying. In the blank graph at right, sketch what you think this frequency distribution might look like if the same people could study for 10 minutes before taking the quiz. Gizmo Warm-up In many cases, it is impractical to investigate every member of a population. Researchers often investigate a smaller sample, or subset, of the population. You can explore the accuracy of samples using the Populations and Samples G Less
