Question

which graph type would be best suited for showing the median percentage of registered voters participating in an election throughout the united states?
a. box-and-whisker plot
b. pie graph
c. scatter plot
d. line graph

Explanation:

A box - and - whisker plot is used to display the five - number summary (minimum, first quartile, median, third quartile, maximum) of a dataset. When we want to show the median percentage of registered voters participating in an election throughout the United States, a box - and - whisker plot can clearly show the median (the middle line in the box) along with the spread of the data. A pie graph is used to show proportions of a whole, a scatter plot is for showing the relationship between two variables, and a line graph is for showing trends over time. Since we are interested in the median and the spread of the data related to voter participation, a box - and - whisker plot is the best choice.

Answer:

A. box - and - whisker plot
