First you wold have to put the numbers in order The ordered data would be 203, 207, 210, 212, 212, 218, 226, 233, 247, 262, 269, 271, 288 You need to find your minimum and maximum points (smallest and largest numbers), first quartile, median (middle number), and third quartile. Go ahead and make a number line ranging from 203 to 288 Plot your minimum and maximum numbers since you know them already 203=minimum, 288=maximum Find your median and then plot it (you can do this by looking at your middle number) Median=262 Put this dot on the number 262 on your number line To find your first quartile, cut the data in half from your median, and then look at the middle of the data set to the left First Quartile=212 Go ahead and plot that on the number line as well You can do the same thing for your third quartile, but instead of looking to the left data set, you have to look at the right data set and find the middle number there Third Quartile=269 Plot this on your number line Finally, to make the "box" part of the plot, you have to connect your first quartile, median, and third quartile with a box Then connect the minimum number to the first quartile with a straight line Do the same thing with the maximum number and the third quartile This will give you your "whiskers"
