Question

which graph type would be best suited for showing the median population for the state capitals in the union?
a. pie graph
b. box-and-whisker plot
c. stem-and-leaf plot
d. scatter plot

Explanation:

A box - and - whisker plot is used to display the five - number summary of a dataset (minimum, first quartile, median, third quartile, maximum). So, to show the median population of state capitals, a box - and - whisker plot is the most suitable as it directly shows the median. A pie graph is for showing proportions of a whole, a stem - and - leaf plot is good for showing the distribution of data but not as direct for showing the median, and a scatter plot is for showing the relationship between two variables.

Answer:

B. box - and - whisker plot
