The correct answer is:
A box and whisker plot
Explanation:
A box and whisker plot, or a box plot, displays what is called the "five number summary." This includes:
Median; LQ (lower quartile, or the median of the lower half of data); UQ (upper quartile, or the median of the upper half of data); lowest value; and highest value.
This will show the spread of data, and the mean can easily be added to this diagram.
