Pease give detailed solution.

Answer 1

The hardest thing about doing this by hand is ordering the data from least to greatest. After ordering the data, find the first, second and third quartiles. The center of the box will be at the second quartile; the box will start at the first quartile and end at the third. From the box you will extend lines that go to the bottom value and maximum value. Hope that helps.
