Homework for Tuesday, Sept. 29

Assignment: 3 Box Plots
This is the complex graphing of 5 numbers that probably doesn't quite fully make sense to you yet.  That's OKAY!!!  The point is that you are going to create these graphs using the 5 number summaries you have and then we will talk about them in class on Wednesday.
1) Page Set-Up
*Turn your page in the same way you set up for your histograms. (we did this in class today)  Mark your scale as "1 box = 1 year"
*Along the bottom of your page should be your horizontal axis labeled with the coin years.  Make sure your coins are listed from newest (top) to oldest (bottom).
*Make sure your years are listed on the LINES of the graph paper.
*I like to list my coins in increments of 5 years and I often draw a bold line marking those increments so I can see it as I work across my page.
*You will draw three box plots total, one in each color; you have room, but the exact width of your boxes is not important.
2) Making Your Box Plots
Your box plots will stretch on your page from the top (2015) to the oldest coin data point at the bottom.
*You will need the 5-number summary you created for yourself, your partner's 5 number summary, and the your class 5-number summaries.  (Click HERE for the class 5-number summaries).
*Make one box plot at a time; you began with your own in class today. 
-----First mark the 5 data points on your page.  Connect the whiskers (one at each end) and draw the box (with the median going through your middle point) using those 5 points as your markers.   I like to make my box plots 4 - 6 boxes in width, but that's up to whatever looks good to you.----
*If you would like to see again what a box plot looks like, click HERE.  That's the general picture; all box plots look about the same (shape), but come in different sizes depending upon the data you are using.  This is one of the things you should try to figure out, by the way ... if it's in quarters, why aren't they all the same size?  Hmmm...
*For more detailed directions on how to do this, click HERE.
That's really it for that.  Box plots are quick and simple to draw once you get the hang of them. 
Due Wednesday, but you will not hand them in to the basket at the beginning of class.
Be prepared to discuss what you think you see!
