Box and Whisker Plots a la Shmoop
And we're back to... The Smell. It's the show where a panel of judges and you, the home
viewer, get to vote on which celebrity smells the best.
There's a scratch-n-sniff card in TV Guide. Here are the scores for last night's show...
Let's create a box-and-whisker plot for the judges' scores.
While we take another sniff and compare our scores with the judges', it might help you
to put them in numerical order and find the median, or the middle score.
But uh oh... because we have an even amount of data, there are TWO middle numbers. Thirty-nine
and forty-four. So to find the true middle number, we can add the two middle numbers
together and divide by two to get the median...
39 plus 44 equals 83... and 83 divided by 2 equals... forty-one point five.
Another way of saying the median, is "Quartile Two," which would be a great name for a fragrance.
Now we want to find the median of the celebrities who are less than quartile two...
...also known as "quartile one" or "rancid." They must have just come on set after working
out...
The two middle scores in this instance are thirty-eight and thirty-six.
Add them together and divide by two to get the median of quartile one... 38 plus 36 equals
74... and 74 divided by 2 equals 37.
Now do the same for the upper quartile, or "quartile three."
50 plus 47 equals 97... and 97 divided by 2 equals 48.5.
The median for quartile three is forty-eight point five.
Now just note the extreme values, which are the bottom and top scores, Ben with 32, and
Bradley with 52.
Sorry, Ben, looks like you got snubbed by The Smell, too.
You can use this data to create your chart, which should look like this...
And you're done! Make sure to call in and text your votes. We hear one lucky viewer
will be chosen to win a Smell-O-Vision TV!
