how the heck do i make a box and whisker plot?

So what you do is get you lower extreme (LE) put a dot on a number line where that is. Then you get your lower quartile (LQ) and put another dot on a number line where that number is. Then get you median (M) and put a for on the number line where that number is. Then get you upper quartile (UQ) put a dot on the number line where that number is. Then get your upper extreme (UE) and put a dot on the number line where that number would be. Now draw a line through the median. Then draw a box on the dots starting at the LQ to the UQ so that it is a box.

Heres an idea which I think is easy. Google it.
