Assignments: Paper Airplane Boxplot Stuff
a) Draw a Boxplot on your Scatterplot
Using the scatterplot you created in your computer class, you are to draw a box plot around it in the way we went over in class. Hopefully you not only observed my example, you began the steps in class or took notes on your partner's work in progress. In review:
*First you will need to create your scale by using a ruler to measure the intervals the program created for you. Most people will use simply 1 M = x centimers, but you can adjust that.
*Your data will be divided into quartiles with 3 data points in each section.
*Your lines will divide the sections by bisecting two consecutive points. We discussed a few methods for doing this including measuring the distance between the two points with a ruler then halving the distance between them, or calculating where the numbers in your 5-number-summary would fall in the graph and marking those points.
*Draw your lines with a ruler and use the entire width of the graph.
*Draw your whiskers extending from the box and up to the highest point.

b) Create a Boxplot on the Given Graph
I gave you a graph on which to put your boxplot for your homework. The link for a copy of that graph is HERE. (I hope it's to scale, because that's the purpose of this activity)
On this graph you will need to plot FIVE points ... aka your 5-number summary which is on the original sheet of your airplane data. We checked our partner's summary in class, but you could also recreate it from your data if you forgot that summary at school. If you forgot how to create the summary from data, scroll back a few blog days and you'll find it. Also important:
*Your scale is given on the sheet as 1 box = 0.25 meters (1/4 of a meter, eh?). MAKE MARKINGS along the side of the graph, even if only the meter points.
*You need to caclulate the central tendencies; you MAY use a calculator for them.
*Your 5-number summary also belongs on the sheet.
*Your boxplot (the box part) should take up the ENTIRE WIDTH of the graph.
*Your lines should be straight - use a ruler, please. Although we are approximating, you also want to be accurate enough that someone can read your graph and understand your values.
*You do NOT need to plot your "dots" in this graph. The purpose of a boxplot is to plot just 5 points! More on that to come later this week ...
Due Tuesday
