Listed below are the numbers of unprovoked shark attacks worldwide for the last several years. Why is it that a dotplot of these data would not be very effective i helping us understand the data? Which of the following graphs would be most effective for these data: dotplot, stemplot, time-series graph, Pareto chart, pie char frequency polygon? 70 54 68 82 79 83 76 73 98 81 Why is it that a dotplot of these data would not be very effective in helping us understand the data? O A. The spread of the data is very small, so it would be nearly impossible to see any differences when represented graphically. B. The data set is too small for a dotplot to reveal important characteristics of the data. c. There are several duplicate values in the data and most graphical methods cannot accurately show duplicate values. O D. Even though the data are numeric, they are actually categorical data because each value is discrete. Which of the following graphs would be most effective for these data:…
