Question

Which is the correct box-and-whisker plot for the following data set?

35, 28, 43, 32, 37, 35, 31, 25, 40, 36

Answer 1

Attached the graph.

Explanation:

Step 1 : Rewrite the observation in ascending order.

25, 28, 31, 32,35, 35, 36, 37, 40, 43

Step 2 : Find out the median of the given observation. It should be the center value.

Median (Q2) = 35

Step 3 : Median separates the observation in to two parts; find out the median(Q1) of the fist half and find out the median(Q3) of second half.

Q1 = 31

Q3 = 37

Minimum = 25

Maximum = 40

Now let's plot the box-and-whisker plot.

Here with I have attached the box-and-whisker plot.

Thank you.
