Answer:
The best type of graph for displaying the range of a data set is a box-and-whisker plot. A box-and-whisker plot is a type of graphical display that shows the distribution of a set of data. It uses a box to represent the middle 50% of the data, with a line inside the box to represent the median. Whiskers extend from the box to show the range of the data outside the box.
A pie chart is best used for displaying proportions or percentages, and would not be suitable for showing the range of a data set.
A bar graph is best used for displaying categorical data, such as comparing the frequency of different categories, and would not be suitable for displaying the range of a data set.
A stem-and-leaf plot is useful for showing the distribution of a set of data, but may not be the best option for displaying the range of the data set.
