Box plot
A box plot is a visual graph that is used to display the median, lower and upper quartiles, and lower and upper extremes of a set of data.
Therefore, let's arrange the data in ascending order.
8, 12, 12, 13, 15, 17, 19, 20
median = 13 + 15 / 2 = 28 / 2 = 14
upper extreme = 20
lower extreme = 8
Therefore, the box plot that represent the data above is the second box plot.
