Which of the following graphs would be most effective for these data: dotplot, stemplot, time-series graph, Pareto chart, pie chart, frequency polygon? A. A time-series graph would be most effective, since the data are listed in order over a period of several years. B. A stemplot would be most effective, since it is important to be able to recreate the original list of values. C. A Pareto chart would be most effective, since the data are categorical data. D. A frequency polygon would be most effective, since the data are listed in order over a period of several years. E. A dotplot would be most effective, since it is important to be able to recreate the original list of values. F. A pie chart would be most effective, since the data are categorical data
