Unfortunately, I cannot physically draw a box-and-whisker plot on the computer, but I can explain how.

First, draw a number line and label it so it includes all of your data values.

Second, determine the lower extreme. Draw a dot above the number on your number line.

Third, determine the median. Draw a dot above the number on your number line.

Fourth, calculate the second quartile. After drawing a dot above the number on your number line, draw a short line that goes through your dot and then connect the lower extreme's dot to the second quartile dot. Draw a line of the same length through the median and connect the two lines at the top and bottom.

Fifth, identify the upper extreme and draw a dot above the number on the number line.

Sixth, calculate the third quartile. Then follow the same steps as with the second quartile.
