Answer 1

C. A box plot is best for displaying the spread of data above and below the​ median, so Yuki should use a box plot.

Explanation:

Neither dot plot nor histogram shows the median of data, but box plot it does. Also, box plots show the how spread data is from minimum value to first quartile, from first quartile to median, from median to third quartile and from third quartile to maximum value.
