Quizplus · Accepted Answer

Charts that indicate changes in central tendency show how the average or typical value of a variable changes over time or across different groups. Examples of central tendency charts include line graphs showing changes in mean or median values, as well as bar graphs showing changes in mode or other measures of central tendency. Charts that show changes in variation (A) may include scatterplots or other graphs that illustrate how much the values of a variable differ from each other at different times or in different groups, while charts that show natural variations (C) might include charts that illustrate how different species or populations vary in size or other characteristics over time. Charts that show numbers of defects (D) might include control charts or other quality control tools that track the number of defects or errors in a production process over time.
